The kthread code provides an infrastructure which manages the preferred
affinity of unbound kthreads (node or custom cpumask) against housekeeping (CPU isolation) constraints and CPU hotplug events. One crucial missing piece is the handling of cpuset: when an isolated partition is created, deleted, or its CPUs updated, all the unbound kthreads in the top cpuset become indifferently affine to _all_ the non-isolated CPUs, possibly breaking their preferred affinity along the way. Solve this with performing the kthreads affinity update from cpuset to the kthreads consolidated relevant code instead so that preferred affinities are honoured and applied against the updated cpuset isolated partitions. The dispatch of the new isolated cpumasks to timers, workqueues and kthreads is performed by housekeeping, as per the nice Tejun's suggestion. As a welcome side effect, HK_TYPE_DOMAIN then integrates both the set from boot defined domain isolation (through isolcpus=) and cpuset isolated partitions. Housekeeping cpumasks are now modifiable with a specific RCU based synchronization. A big step toward making nohz_full= also mutable through cpuset in the future. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEd76+gtGM8MbftQlOhSRUR1COjHcFAmmE0mYbFIAAAAAABAAO bWFudTIsMi41KzEuMTEsMiwyAAoJEIUkVEdQjox36eMP/0Ls/ArfYVi/MNAXWlpy rAt6m9Y/X9GBcDM/VI9BXq1ZX4qEr2XjJ8UUb8cM08uHEAt0ErlmpRxREwJFrKbI H4jzg5EwO0D0c6MnvgQJEAwkHxQVIjsxG9DovRIjxyW4ycx3aSsRg/f2VKyWoLvY 7ZT7CbLFE+I/MQh2ZgUu/9pnCDQVR2anss2WYIej5mmgFL5pyEv3YvYgKYVyK08z sXyNxpP976g2d9ECJ9OtFJV9we6mlqxlG0MVCiv/Uxh7DBjxWWPsLvlmLAXggQ03 +0GW+nnutDaKz83pgS7Z4zum/+Oa+I1dTLIN27pARUNcMCYip7njM2KNpJwPdov3 +fAIODH2JVX1xewT+U1cCq6gdI55ejbwdQYGFV075dKBUxKQeIyrghvfC3Ga6aKQ Gw3y68jdrXOw6iyfHR5k/0Mnu2/FDKUW2fZxLKm55PvNZP5jQFmSlz9wyiwwyb3m UUSgThj6Ozodxks8hDX41rGVezCcm1ni+qNSiNIs8HPaaZQrwbnvKHQFBBJHQzJP rJ39VWBx3Hq/ly71BOR6pCzoZsfS1f85YKhJ4vsfjLO6BfhI16nBat89eROSRKcz XptyWqW0PgAD0teDuMCTPNuUym/viBHALXHKuSO12CIizacvftiGcmaQNPlLiiFZ /Dr2+aOhwYw3UD6djn3u94M9 =nWGh -----END PGP SIGNATURE----- Merge tag 'kthread-for-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull kthread updates from Frederic Weisbecker: "The kthread code provides an infrastructure which manages the preferred affinity of unbound kthreads (node or custom cpumask) against housekeeping (CPU isolation) constraints and CPU hotplug events.

Pull power management updates from Rafael Wysocki:
"By the number of commits, cpufreq is the leading party (again) and the
most visible change there is the removal of the omap-cpufreq driver
that has not been used for a long time (good riddance). There are also
quite a few changes in the cppc_cpufreq driver, mostly related to
fixing its frequency invariance engine in the case when the CPPC
registers used by it are not in PCC. In addition to that, support for
AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev
list is updated for some platforms. The remaining cpufreq changes are
assorted fixes and cleanups.
Next up is cpuidle and the changes there are dominated by intel_idle
driver updates, mostly related to the new command line facility
allowing users to adjust the list of C-states used by the driver.
There are also a few updates of cpuidle governors, including two menu
governor fixes and some refinements of the teo governor, and a
MAINTAINERS update adding Christian Loehle as a cpuidle reviewer.
[Thanks for stepping up Christian!]
The most significant update related to system suspend and hibernation
is the one to stop freezing the PM runtime workqueue during system PM
transitions which allows some deadlocks to be avoided. There is also a
fix for possible concurrent bit field updates in the core device
suspend code and a few other minor fixes.
Apart from the above, several drivers are updated to discard the
return value of pm_runtime_put() which is going to be converted to a
void function as soon as everybody stops using its return value, PL4
support for Ice Lake is added to the Intel RAPL power capping driver,
and there are assorted cleanups, documentation fixes, and some
cpupower utility improvements.

Pull ACPI updates from Rafael Wysocki:
"This one is significantly larger than previous ACPI support pull
requests because several significant updates have coincided in it.
First, there is a routine ACPICA code update, to upstream version
20251212, but this time it covers new ACPI 6.6 material that has not
been covered yet. Among other things, it includes definitions of a few
new ACPI tables and updates of some others, like the GICv5 MADT
structures and ARM IORT IWB node definitions that are used for adding
GICv5 ACPI probing on ARM (that technically is IRQ subsystem material,
but it depends on the ACPICA changes, so it is included here). The
latter alone adds a few hundred lines of new code.
Second, there is an update of ACPI _OSC handling including a fix that
prevents failures from occurring in some corner cases due to careless
handling of _OSC error bits.
On top of that, the "system resource" ACPI device objects with the
PNP0C01 and PNP0C02 are now going to be handled by the ACPI core
device enumeration code instead of handing them over to the legacy PNP
system driver which causes device enumeration issues to occur. Some of
those issues have been worked around in device drivers and elsewhere
and those workarounds should not be necessary any more, so they are
going away.
Moreover, the time has come to convert all "core ACPI" device drivers
that were still using struct acpi_driver objects for device binding
into proper platform drivers that use struct platform_driver for this
purpose. These updates are accompanied by some requisite core ACPI
device enumeration code changes.
Next, there are ACPI APEI updates, including changes to avoid excess
overhead in the NMI handler and in SEA on the ARM side, changes to
unify ACPI-based HW error tracing and logging, and changes to prevent
APEI code from reaching out of its allocated memory.
There are also some ACPI power management updates, mostly related to
the ACPI cpuidle support in the processor driver, suspend-to-idle
handling on systems with ACPI support and to ACPI PM of devices.
In addition to the above, bugs are fixed and the code is cleaned up in
assorted places all over.
Specifics:
- Update the ACPICA code in the kernel to upstream version 20251212

Pull bounce buffer dio for stable pages from Jens Axboe:
"This adds support for bounce buffering of dio for stable pages. This
was all done by Christoph. In his words:
This series tries to address the problem that under I/O pages can be
modified during direct I/O, even when the device or file system
require stable pages during I/O to calculate checksums, parity or data
operations. It does so by adding block layer helpers to bounce buffer
an iov_iter into a bio, then wires that up in iomap and ultimately
XFS.
The reason that the file system even needs to know about it, is
because reads need a user context to copy the data back, and the
infrastructure to defer ioends to a workqueue currently sits in XFS.
I'm going to look into moving that into ioend and enabling it for
other file systems. Additionally btrfs already has it's own
infrastructure for this, and actually an urgent need to bounce buffer,
so this should be useful there and could be wire up easily. In fact
the idea comes from patches by Qu that did this in btrfs.
This patch fixes all but one xfstests failures on T10 PI capable
devices (generic/095 seems to have issues with a mix of mmap and
splice still, I'm looking into that separately), and make qemu VMs
running Windows, or Linux with swap enabled fine on an XFS file on a
device using PI.
Performance numbers on my (not exactly state of the art) NVMe PI test
setup:
Sequential reads using io_uring, QD=16.
Bandwidth and CPU usage (usr/sys):
| size | zero copy | bounce |
+------+--------------------------+--------------------------+
| 4k | 1316MiB/s (12.65/55.40%) | 1081MiB/s (11.76/49.78%) |
| 64K | 3370MiB/s ( 5.46/18.20%) | 3365MiB/s ( 4.47/15.68%) |
| 1M | 3401MiB/s ( 0.76/23.05%) | 3400MiB/s ( 0.80/09.06%) |
+------+--------------------------+--------------------------+
Sequential writes using io_uring, QD=16.
Bandwidth and CPU usage (usr/sys):
| size | zero copy | bounce |
+------+--------------------------+--------------------------+
| 4k | 882MiB/s (11.83/33.88%) | 750MiB/s (10.53/34.08%) |
| 64K | 2009MiB/s ( 7.33/15.80%) | 2007MiB/s ( 7.47/24.71%) |
| 1M | 1992MiB/s ( 7.26/ 9.13%) | 1992MiB/s ( 9.21/19.11%) |
+------+--------------------------+--------------------------+
Note that the 64k read numbers look really odd to me for the baseline
zero copy case, but are reproducible over many repeated runs.
The bounce read numbers should further improve when moving the PI
validation to the file system and removing the double context switch,
which I have patches for that will sent out soon"

Merge tag 'for-7.0/block-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull block updates from Jens Axboe:
- Support for batch request processing for ublk, improving the
efficiency of the kernel/ublk server communication. This can yield
nice 7-12% performance improvements
- Support for integrity data for ublk
- Various other ublk improvements and additions, including a ton of
selftests additions and updated
- Move the handling of blk-crypto software fallback from below the
block layer to above it. This reduces the complexity of dealing with
bio splitting
- Series fixing a number of potential deadlocks in blk-mq related to
the queue usage counter and writeback throttling and rq-qos debugfs
handling
- Add an async_depth queue attribute, to resolve a performance
regression that's been around for a qhilw related to the scheduler
depth handling
- Only use task_work for IOPOLL completions on NVMe, if it is necessary
to do so. An earlier fix for an issue resulted in all these
completions being punted to task_work, to guarantee that completions
were only run for a given io_uring ring when it was local to that
ring. With the new changes, we can detect if it's necessary to use
task_work or not, and avoid it if possible.
- rnbd fixes:
- Fix refcount underflow in device unmap path
- Handle PREFLUSH and NOUNMAP flags properly in protocol
- Fix server-side bi_size for special IOs
- Zero response buffer before use
- Fix trace format for flags
- Add .release to rnbd_dev_ktype
- MD pull requests via Yu Kuai
- Fix raid5_run() to return error when log_init() fails
- Fix IO hang with degraded array with llbitmap
- Fix percpu_ref not resurrected on suspend timeout in llbitmap
- Fix GPF in write_page caused by resize race
- Fix NULL pointer dereference in process_metadata_update
- Fix hang when stopping arrays with metadata through dm-raid
- Fix any_working flag handling in raid10_sync_request
- Refactor sync/recovery code path, improve error handling for
badblocks, and remove unused recovery_disabled field
- Consolidate mddev boolean fields into mddev_flags
- Use mempool to allocate stripe_request_ctx and make sure
max_sectors is not less than io_opt in raid5
- Fix return value of mddev_trylock
- Fix memory leak in raid1_run()
- Add Li Nan as mdraid reviewer
- Move phys_vec definitions to the kernel types, mostly in preparation
for some VFIO and RDMA changes
- Improve the speed for secure erase for some devices
- Various little rust updates
- Various other minor fixes, improvements, and cleanups

As a result, things like containers and systemd that apply seccomp filters, can't filter io_uring operations. That leaves them with just one choice if filtering is critical - filter the actual io_uring_setup(2) system call to simply disallow io_uring. That's rather unfortunate, and has limited us because of it. io_uring already has some filtering support. It requires the ring to be setup in a disabled state, and then a filter set can be applied. This filter set is completely bi-modal - an opcode is either enabled or it's not. Once a filter set is registered, the ring can be enabled. This is very restrictive, and it's not useful at all to systemd or containers which really want both broader and more specific control. This first adds support for cBPF filters for opcodes, which enables tighter control over what exactly a specific opcode may do. As examples, specific support is added for IORING_OP_OPENAT/OPENAT2, allowing filtering on resolve flags. And another example is added for IORING_OP_SOCKET, allowing filtering on domain/type/protocol. These are both common use cases. cBPF was chosen rather than eBPF, because the latter is often restricted in containers as well. These filters are run post the init phase of the request, which allows filters to even dip into data that is being passed in struct in user memory, as the init side of requests make that data stable by bringing it into the kernel. This allows filtering without needing to copy this data twice, or have filters etc know about the exact layout of the user data. The filters get the already copied and sanitized data passed. On top of that support is added for per-task filters, meaning that any ring created with a task that has a per-task filter will get those filters applied when it's created. These filters are inherited across fork as well. Once a filter has been registered, any further added filters may only further restrict what operations are permitted. Filters cannot change the return value of an operation, they can only permit or deny it based on the contents" * tag 'io_uring-bpf-restrictions.4-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: io_uring: allow registration of per-task restrictions io_uring: add task fork hook io_uring/bpf_filter: add ref counts to struct io_bpf_filter io_uring/bpf_filter: cache lookup table in ctx->bpf_filters io_uring/bpf_filter: allow filtering on contents of struct open_how io_uring/net: allow filtering on IORING_OP_SOCKET data io_uring: add support for BPF filtering for opcode restrictions |

Previously it was singly listed, which meant that to complete request N in the chain 0..N-1 had to have completed first. With a doubly linked list we can complete whatever request completes in that order, rather than need to wait for a consecutive range to be available. This reduces latencies. - Improve the restriction setup and checking. Mostly in preparation for adding further features on top of that. Coming in a separate pull request. - Split out task_work and wait handling into separate files. These are mostly nicely abstracted already, but still remained in the io_uring.c file which is on the larger side. - Use GFP_KERNEL_ACCOUNT in a few more spots, where appropriate. - Ensure even the idle io-wq worker exits if a task no longer has any rings open. - Add support for a non-circular submission queue. By default, the SQ ring keeps moving around, even if only a few entries are used for each submission. This can be wasteful in terms of cachelines. If IORING_SETUP_SQ_REWIND is set for the ring when created, each submission will start at offset 0 instead of where we last left off doing submissions. - Various little cleanups * tag 'for-7.0/io_uring-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (30 commits) io_uring/kbuf: fix memory leak if io_buffer_add_list fails io_uring: Add SPDX id lines to remaining source files io_uring: allow io-wq workers to exit when unused io_uring/io-wq: add exit-on-idle state io_uring/net: don't continue send bundle if poll was required for retry io_uring/rsrc: use GFP_KERNEL_ACCOUNT consistently io_uring/futex: use GFP_KERNEL_ACCOUNT for futex data allocation io_uring/io-wq: handle !sysctl_hung_task_timeout_secs io_uring: fix bad indentation for setup flags if statement io_uring/rsrc: take unsigned index in io_rsrc_node_lookup() io_uring: introduce non-circular SQ io_uring: split out CQ waiting code into wait.c io_uring: split out task work code into tw.c io_uring/io-wq: don't trigger hung task for syzbot craziness io_uring: add IO_URING_EXIT_WAIT_MAX definition io_uring/sync: validate passed in offset io_uring/eventfd: remove unused ctx->evfd_last_cq_tail member io_uring/timeout: annotate data race in io_flush_timeouts() io_uring/uring_cmd: explicitly disallow cancelations for IOPOLL io_uring: fix IOPOLL with passthrough I/O ... |

Pull erofs updates from Gao Xiang:
"In this cycle, inode page cache sharing among filesystems on the same
machine is now supported, which is particularly useful for
high-density hosts running tens of thousands of containers.
In addition, we fully isolate the EROFS core on-disk format from other
optional encoded layouts since the core on-disk part is designed to be
simple, effective, and secure. Users can use the core format to build
unique golden immutable images and import their filesystem trees
directly from raw block devices via DMA, page-mapped DAX devices,
and/or file-backed mounts without having to worry about unnecessary
intrinsic consistency issues found in other generic filesystems by
design. However, the full vision is still working in progress and will
spend more time to achieve final goals.
There are other improvements and bug fixes as usual, as listed below:
- Support inode page cache sharing among filesystems
- Formally separate optional encoded (aka compressed) inode layouts
(and the implementations) from the EROFS core on-disk aligned plain
format for future zero-trust security usage
- Improve performance by caching the fact that an inode does not have
a POSIX ACL
- Improve LZ4 decompression error reporting
- Enable LZMA by default and promote DEFLATE and Zstandard algorithms
out of EXPERIMENTAL status
- Switch to inode_set_cached_link() to cache symlink lengths
- random bugfixes and minor cleanups"

HFS+ fixes of xfstests failures.
- fix an issue reported by syzbot triggering BUG_ON() in the case of

- fix memory leaks in the mount logic of HFS/HFS+ file systems. When

by changing the allocation pattern of sb->s_fs_info (Mehdi Ben Hadj
Khelifa)
- fix hfs_bnode_create() by returning ERR_PTR(-EEXIST) instead of
the node pointer when it's already hashed. This avoids a double
unload_nls() on mount failure (suggested by Shardul Bankar)
- set inode's mode as regular file for system inodes (Tetsuo Handa)
The rest fix failures in generic/020, generic/037, generic/062,
generic/480, and generic/498 xfstests for the case of HFS+ file

Pull btrfs updates from David Sterba:
"User visible changes, feature updates:
- when using block size > page size, enable direct IO
- fallback to buffered IO if the data profile has duplication,
workaround to avoid checksum mismatches on block group profiles
with redundancy, real direct IO is possible on single or RAID0
- redo export of zoned statistics, moved from sysfs to
/proc/pid/mountstats due to size limitations of the former
Experimental features:
- remove offload checksum tunable, intended to find best way to do it
but since we've switched to offload to thread for everything we
don't need it anymore
- initial support for remap-tree feature, a translation layer of
logical block addresses that allow changes without moving/rewriting
blocks to do eg. relocation, or other changes that require COW
Notable fixes:
- automatic removal of accidentally leftover chunks when
free-space-tree is enabled since mkfs.btrfs v6.16.1
- zoned mode:
- do not try to append to conventional zones when RAID is mixing
zoned and conventional drives
- fixup write pointers when mixing zoned and conventional on
DUP/RAID* profiles
- when using squota, relax deletion rules for qgroups with 0 members
to allow easier recovery from accounting bugs, also add more checks
to detect bad accounting
- fix periodic reclaim scanning, properly check boundary conditions
not to trigger it unexpectedly or miss the time to run it
- trim:
- continue after first error
- change reporting to the first detected error
- add more cancellation points
- reduce contention of big device lock that can block other
operations when there's lots of trimmed space
- when chunk allocation is forced (needs experimental build) fix
transaction abort when unexpected space layout is detected
Core:
- switch to crypto library API for checksumming, removed module
dependencies, pointer indirections, etc.
- error handling improvements
- adjust how and where transaction commit or abort are done and are
maybe not necessary
- minor compression optimization to skip single block ranges
- improve how compression folios are handled
- new and updated selftests
- cleanups, refactoring:
- auto-freeing and other automatic variable cleanup conversion
- structure size optimizations
- condition annotations"

Pull misc vfs updates from Christian Brauner:
"This contains a mix of VFS cleanups, performance improvements, API
fixes, documentation, and a deprecation notice.
Scalability and performance:
- Rework pid allocation to only take pidmap_lock once instead of
twice during alloc_pid(), improving thread creation/teardown
throughput by 10-16% depending on false-sharing luck. Pad the
namespace refcount to reduce false-sharing
- Track file lock presence via a flag in ->i_opflags instead of
reading ->i_flctx, avoiding false-sharing with ->i_readcount on
open/close hot paths. Measured 4-16% improvement on 24-core
open-in-a-loop benchmarks
- Use a consume fence in locks_inode_context() to match the
store-release/load-consume idiom, eliminating a hardware fence on
some architectures
- Annotate cdev_lock with __cacheline_aligned_in_smp to prevent
false-sharing
- Remove a redundant DCACHE_MANAGED_DENTRY check in
__follow_mount_rcu() that never fires since the caller already
verifies it, eliminating a 100% mispredicted branch
- Fix a 100% mispredicted likely() in devcgroup_inode_permission()
that became wrong after a prior code reorder
Bug fixes and correctness:
- Make insert_inode_locked() wait for inode destruction instead of
skipping, fixing a corner case where two matching inodes could
exist in the hash
- Move f_mode initialization before file_ref_init() in alloc_file()
to respect the SLAB_TYPESAFE_BY_RCU ordering contract
- Add a WARN_ON_ONCE guard in try_to_free_buffers() for folios with
no buffers attached, preventing a null pointer dereference when
AS_RELEASE_ALWAYS is set but no release_folio op exists
- Fix select restart_block to store end_time as timespec64, avoiding
truncation of tv_sec on 32-bit architectures
- Make dump_inode() use get_kernel_nofault() to safely access inode
and superblock fields, matching the dump_mapping() pattern
API modernization:
- Make posix_acl_to_xattr() allocate the buffer internally since
every single caller was doing it anyway. Reduces boilerplate and
unnecessary error checking across ~15 filesystems
- Replace deprecated simple_strtoul() with kstrtoul() for the
ihash_entries, dhash_entries, mhash_entries, and mphash_entries
boot parameters, adding proper error handling
- Convert chardev code to use guard(mutex) and __free(kfree) cleanup
patterns
- Replace min_t() with min() or umin() in VFS code to avoid silently
truncating unsigned long to unsigned int
- Gate LOOKUP_RCU assertions behind CONFIG_DEBUG_VFS since callers
already check the flag
Deprecation:
- Begin deprecating legacy BSD process accounting (acct(2)). The
interface has numerous footguns and better alternatives exist
(eBPF)
Documentation:
- Fix and complete kernel-doc for struct export_operations, removing
duplicated documentation between ReST and source
- Fix kernel-doc warnings for __start_dirop() and ilookup5_nowait()
Testing:
- Add a kunit test for initramfs cpio handling of entries with
filesize > PATH_MAX
Misc:
- Add missing <linux/init_task.h> include in fs_struct.c"

When set, statmount() returns mount information for the mount the fd resides on — including detached mounts (unmounted via umount2(MNT_DETACH)). For detached mounts the STATMOUNT_MNT_POINT and STATMOUNT_MNT_NS_ID mask bits are cleared since neither is meaningful. The capability check is skipped for STATMOUNT_BY_FD since holding an fd already implies prior access to the mount and equivalent information is available through fstatfs() and /proc/pid/mountinfo without privilege. Includes comprehensive selftests covering both attached and detached mount cases. - fs: Remove internal old mount API code (1 patch) Now that every in-tree filesystem has been converted to the new mount API, remove all the legacy shim code in fs_context.c that handled unconverted filesystems. This deletes ~280 lines including legacy_init_fs_context(), the legacy_fs_context struct, and associated wrappers. The mount(2) syscall path for userspace remains untouched. Documentation references to the legacy callbacks are cleaned up. - mount: add OPEN_TREE_NAMESPACE to open_tree() Container runtimes currently use CLONE_NEWNS to copy the caller's entire mount namespace — only to then pivot_root() and recursively unmount everything they just copied. With large mount tables and thousands of parallel container launches this creates significant contention on the namespace semaphore. OPEN_TREE_NAMESPACE copies only the specified mount tree (like OPEN_TREE_CLONE) but returns a mount namespace fd instead of a detached mount fd. The new namespace contains the copied tree mounted on top of a clone of the real rootfs. This functions as a combined unshare(CLONE_NEWNS) + pivot_root() in a single syscall. Works with user namespaces: an unshare(CLONE_NEWUSER) followed by OPEN_TREE_NAMESPACE creates a mount namespace owned by the new user namespace. Mount namespace file mounts are excluded from the copy to prevent cycles.

cannot be unmounted. Userspace has to recursively delete initramfs
contents manually before continuing boot, using the fragile
switch_root sequence (overmount + chroot).
Add nullfs, a minimal immutable filesystem that serves as the true
root of the mount hierarchy. The mutable rootfs (tmpfs/ramfs) is
mounted on top of it. This allows userspace to simply:
chdir(new_root);
pivot_root(".", ".");
umount2(".", MNT_DETACH);
without the traditional switch_root workarounds. systemd already
handles this correctly. It tries pivot_root() first and falls back
to MS_MOVE only when that fails.
This also means rootfs mounts in unprivileged namespaces no longer
need MNT_LOCKED, since the immutable nullfs guarantees nothing can be
revealed by unmounting the covering mount.
nullfs is a single-instance filesystem (get_tree_single()) marked
SB_NOUSER | SB_I_NOEXEC | SB_I_NODEV with an immutable empty root
directory. This means sooner or later it can be used to overmount
other directories to hide their contents without any additional
protection needed.
We enable it unconditionally. If we see any real regression we'll
hide it behind a boot option.
nullfs has extensions beyond this in the future. It will serve as a
concept to support the creation of completely empty mount namespaces -
which is work coming up in the next cycle"
* tag 'vfs-7.0-rc1.nullfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
fs: use nullfs unconditionally as the real rootfs
docs: mention nullfs

Btrfs has carried private copies of the VFS may_delete() and

drifted out of sync with the VFS originals — btrfs_may_delete() is

Errors are queued via mempools and queue_work to avoid holding filesystem locks in the notification path; unmount waits for pending events to drain. A new super_operations::report_error callback lets filesystem drivers respond to file I/O errors themselves (to be used by an upcoming XFS self-healing patchset).

RCU changes for v7.0
RCU Tasks Trace:
Re-implement RCU tasks trace in term of SRCU-fast, not only more than 500 lines
of code are saved because of the reimplementation, a new set of API,
rcu_read_{,un}lock_tasks_trace(), becomes possible as well. Compared to the
previous rcu_read_{,un}lock_trace(), the new API avoid the task_struct accesses
thanks to the SRCU-fast semantics. As a result, the old
rcu_read{,un}lock_trace() API is now deprecated.
RCU Torture Test:
- Multiple improvements on kvm-series.sh (parallel run and progress showing
metrics)
- Add context checks to rcu_torture_timer().
- Make config2csv.sh properly handle comments in .boot files.
- Include commit discription in testid.txt.
Miscellaneous RCU changes:
- Reduce synchronize_rcu() latency by reporting GP kthread's CPU QS early.
- Use suitable gfp_flags for the init_srcu_struct_nodes().
- Fix rcu_read_unlock() deadloop due to softirq.
- Correctly compute probability to invoke ->exp_current() in rcutorture.
- Make expedited RCU CPU stall warnings detect stall-end races.
RCU nocb:
- Remove unnecessary WakeOvfIsDeferred wake path and callback overload
handling.
- Extract nocb_defer_wakeup_cancel() helper.
