cgroup/cpuset: Free sched domains on rebuild guard failure
generate_sched_domains() returns sched-domain masks and optional attributes that are normally handed to partition_sched_domains(), which takes ownership of them. rebuild_sched_domains_locked() has a WARN guard after generate_sched_domains() and before partition_sched_domains() to avoid passing offline CPUs into the scheduler domain rebuild path. If that guard fires, the function currently returns directly without freeing the generated doms and attr. Free the generated sched-domain masks and attributes before returning from the guard failure path.

cgroup: pair max limit READ_ONCE() with WRITE_ONCE()
cgroup.max.descendants and cgroup.max.depth are shown through seq_file. Their show callbacks read cgrp->max_descendants and cgrp->max_depth with READ_ONCE(), respectively. The corresponding write callbacks update the same scalar fields while holding the cgroup lock, but the seq_file show path does not serialize against those stores. This leaves the lockless show-side loads annotated with READ_ONCE(), while the corresponding stores remain plain stores. Use WRITE_ONCE() for the updates so the intended lockless access is marked consistently on both sides. This does not change locking, ordering, or user-visible semantics.

selftests/cgroup: enable memory controller in hugetlb memcg test
test_hugetlb_memcg creates a child cgroup and then writes memory.max and memory.swap.max. When the test is run standalone, the memory controller may not be enabled in the test root cgroup's subtree_control. In that case, the child cgroup is created without the memory control files, and the test fails during setup before reaching the hugetlb memcg accounting checks. Skip the test when the memory controller is unavailable. Otherwise, enable it in subtree_control before creating the test cgroup.

cgroup/rdma: add rdma.events.local for per-cgroup allocation failure attribution
Add per-cgroup local event counters to track RDMA resource limit exhaustion from the perspective of individual cgroups. The rdma.events.local file reports two per-resource counters: - max: number of times this cgroup's limit was the one that blocked an allocation in the subtree - alloc_fail: number of allocation attempts originating from this cgroup that failed due to an ancestor's limit This mirrors the design of pids.events.local, where events are attributed to the cgroup that imposed the limit, not necessarily the cgroup where the allocation was attempted. Also extend rdma.events with a hierarchical alloc_fail counter that tracks allocation failures propagating upward from the requesting cgroup, complementing the existing max counter, so that rdma.events and rdma.events.local share the same output format.

cgroup/cpuset: Reset DL migration state on can_attach() failure
cpuset_can_attach() accumulates temporary SCHED_DEADLINE migration
state in the destination cpuset while walking the taskset.
If a later task_can_attach() or security_task_setscheduler() check
fails, cgroup_migrate_execute() treats cpuset as the failing subsystem
and does not call cpuset_cancel_attach() for it. The partially
accumulated state is then left behind and can be consumed by a later
attach, corrupting cpuset DL task accounting and pending DL bandwidth
accounting.
Reset the pending DL migration state from the common error exit when
ret is non-zero. Successful can_attach() keeps the state for
cpuset_attach() or cpuset_cancel_attach().

selftests/cgroup: Fix cg_read_strcmp() empty string comparison
cg_read_strcmp() allocated a buffer sized to strlen(expected) + 1,
then passed it to read_text() which calls read(fd, buf, size-1).
When comparing against an empty string (""), strlen("") = 0 gives a
1-byte buffer, and read() is asked to read 0 bytes. The file content
is never actually read, so strcmp("", buf) always returns 0 regardless
of the real content. This caused cg_test_proc_killed() to always
report the cgroup as empty immediately, making OOM tests pass without
verifying that processes were killed.

cgroup/dmem: Return -ENOMEM on failed pool preallocation
get_cg_pool_unlocked() handles allocation failures under dmemcg_lock by
dropping the lock, preallocating a pool with GFP_KERNEL, and retrying the
locked lookup and creation path.
If the fallback allocation fails too, pool remains NULL. Since the loop
condition is while (!pool), the function can keep retrying instead of
propagating the allocation failure to the caller.
Set pool to ERR_PTR(-ENOMEM) when the fallback allocation fails so the
loop exits through the existing common return path. The callers already
handle ERR_PTR() from get_cg_pool_unlocked(), so this restores the
expected error path.

cgroup/cpuset: move PF_EXITING check before __GFP_HARDWALL in cpuset_current_node_allowed()
Since prepare_alloc_pages() unconditionally adds __GFP_HARDWALL for the fast path when cpusets are enabled, the __GFP_HARDWALL check in cpuset_current_node_allowed() causes the PF_EXITING escape path to be skipped on the first allocation attempt. This makes it unreachable in the common case, so dying tasks can get stuck in direct reclaim or even trigger OOM while trying to exit, despite being allowed to allocate from any node. Move the PF_EXITING check before __GFP_HARDWALL so that dying tasks can allocate memory from any node to exit quickly, even when cpusets are enabled. Also update the function comment to reflect the actual behavior of prepare_alloc_pages() and the corrected check ordering.

cgroup/rdma: refactor resource parsing with match_table_t/match_token()
Replace the hand-rolled strsep/strcmp/match_string parsing in
rdmacg_resource_set_max() with a match_table_t and match_token()
pattern, following the convention used by user_proactive_reclaim()
and ioc_cost_model_write().
The old strncmp(value, RDMACG_MAX_STR, strlen(value)) also had two
bugs that are fixed by this refactor:
- It matched "ma" as "max" because strncmp only compared the
shorter strlen(value) bytes.
- It silently accepted "hca_handle=" (empty value) as "max"
because strncmp with n=0 always returns 0.
The match_token() approach also robustly handles extra whitespace in
the input by splitting on " \t\n" and skipping empty tokens.

cgroup/cpuset: record DL BW alloc CPU for attach rollback
cpuset_can_attach() allocates DL bandwidth only when migrating
deadline tasks to a disjoint CPU mask, but cpuset_cancel_attach()
rolls back based only on nr_migrate_dl_tasks. This makes the DL
bandwidth alloc/free paths asymmetric: rollback can call dl_bw_free()
even when no dl_bw_alloc() was done.
Rollback also needs to undo the reservation against the same CPU/root
domain that was charged. Record the CPU used by dl_bw_alloc() and use
that state in cpuset_cancel_attach(). If no allocation happened,
dl_bw_cpu stays at -1 and rollback skips dl_bw_free(). If allocation
did happen, bandwidth is returned to the same CPU/root domain.
Successful attach paths are unchanged. This only fixes failed attach
rollback accounting.

cgroup/rdma: fix integer overflow in rdmacg_try_charge()
The expression `rpool->resources[index].usage + 1` is computed in int
arithmetic before being assigned to s64 variable `new`. When usage equals
INT_MAX (the default "max" value), the addition overflows to INT_MIN.
This negative value then passes the `new > max` check incorrectly,
allowing a charge that should be rejected and corrupting usage to
negative.
Fix by casting usage to s64 before the addition so the arithmetic is
done in 64-bit.

sched/psi: fix race between file release and pressure write
A potential race condition exists between pressure write and cgroup file
release regarding the priv member of struct kernfs_open_file, which
triggers the uaf reported in [1].
Consider the following scenario involving execution on two separate CPUs:
CPU0 CPU1
==== ====
vfs_rmdir()
kernfs_iop_rmdir()
cgroup_rmdir()
cgroup_kn_lock_live()
cgroup_destroy_locked()
cgroup_addrm_files()
cgroup_rm_file()
kernfs_remove_by_name()
kernfs_remove_by_name_ns()
vfs_write() __kernfs_remove()
new_sync_write() kernfs_drain()
kernfs_fop_write_iter() kernfs_drain_open_files()
cgroup_file_write() kernfs_release_file()
pressure_write() cgroup_file_release()
ctx = of->priv;
kfree(ctx);
of->priv = NULL;
cgroup_kn_unlock()
cgroup_kn_lock_live()
cgroup_get(cgrp)
cgroup_kn_unlock()
if (ctx->psi.trigger) // here, trigger uaf for ctx, that is of->priv
The cgroup_rmdir() is protected by the cgroup_mutex, it also safeguards
the memory deallocation of of->priv performed within cgroup_file_release().
However, the operations involving of->priv executed within pressure_write()
are not entirely covered by the protection of cgroup_mutex. Consequently,
if the code in pressure_write(), specifically the section handling the
ctx variable executes after cgroup_file_release() has completed, a uaf
vulnerability involving of->priv is triggered.
Therefore, the issue can be resolved by extending the scope of the
cgroup_mutex lock within pressure_write() to encompass all code paths
involving of->priv, thereby properly synchronizing the race condition
occurring between cgroup_file_release() and pressure_write().
And, if an live kn lock can be successfully acquired while executing
the pressure write operation, it indicates that the cgroup deletion
process has not yet reached its final stage; consequently, the priv
pointer within open_file cannot be NULL. Therefore, the operation to
retrieve the ctx value must be moved to a point *after* the live kn
lock has been successfully acquired.
In another situation, specifically after entering cgroup_kn_lock_live()
but before acquiring cgroup_mutex, there exists a different class of
race condition:
CPU0: write memory.pressure CPU1: write cgroup.pressure=0
=========================== =============================
kernfs_fop_write_iter()
kernfs_get_active_of(of)
pressure_write()
cgroup_kn_lock_live(memory.pressure)
cgroup_tryget(cgrp)
kernfs_break_active_protection(kn)
... blocks on cgroup_mutex
cgroup_pressure_write()
cgroup_kn_lock_live(cgroup.pressure)
cgroup_file_show(memory.pressure, false)
kernfs_show(false)
kernfs_drain_open_files()
cgroup_file_release(of)
kfree(ctx)
of->priv = NULL
cgroup_kn_unlock()
... acquires cgroup_mutex
ctx = of->priv; // may now be NULL
if (ctx->psi.trigger) // NULL dereference
Consequently, there is a possibility that of->priv is NULL, the pressure
write needs to check for this.
Now that the scope of the cgroup_mutex has been expanded, the original
explicit cgroup_get/put operations are no longer necessary, this is
because acquiring/releasing the live kn lock inherently executes a
cgroup get/put operation.

This uses the new infrastructure for 'remote' trace buffers that can be exposed by non-kernel entities such as firmware, and which came through the tracing tree. - Add support for GICv5 Per Processor Interrupts (PPIs), as the starting point for supporting the new GIC architecture in KVM. - Finally add support for pKVM protected guests, where pages are unmapped from the host as they are faulted into the guest and can be shared back from the guest using pKVM hypercalls. Protected guests are created using a new machine type identifier. As the elusive guestmem has not yet delivered on its promises, anonymous memory is also supported. This is only a first step towards full isolation from the host; for example, the CPU register state and DMA accesses are not yet isolated. Because this does not really yet bring fully what it promises, it is hidden behind CONFIG_ARM_PKVM_GUEST + 'kvm-arm.mode=protected', and also triggers TAINT_USER when a VM is created. Caveat emptor. - Rework the dreaded user_mem_abort() function to make it more maintainable, reducing the amount of state being exposed to the various helpers and rendering a substantial amount of state immutable. - Expand the Stage-2 page table dumper to support NV shadow page tables on a per-VM basis. - Tidy up the pKVM PSCI proxy code to be slightly less hard to follow. - Fix both SPE and TRBE in non-VHE configurations so that they do not generate spurious, out of context table walks that ultimately lead to very bad HW lockups. - A small set of patches fixing the Stage-2 MMU freeing in error cases. - Tighten-up accepted SMC immediate value to be only #0 for host SMCCC calls. - The usual cleanups and other selftest churn. LoongArch: - Use CSR_CRMD_PLV for kvm_arch_vcpu_in_kernel(). - Add DMSINTC irqchip in kernel support. RISC-V: - Fix steal time shared memory alignment checks - Fix vector context allocation leak - Fix array out-of-bounds in pmu_ctr_read() and pmu_fw_ctr_read_hi() - Fix double-free of sdata in kvm_pmu_clear_snapshot_area() - Fix integer overflow in kvm_pmu_validate_counter_mask() - Fix shift-out-of-bounds in make_xfence_request() - Fix lost write protection on huge pages during dirty logging - Split huge pages during fault handling for dirty logging - Skip CSR restore if VCPU is reloaded on the same core - Implement kvm_arch_has_default_irqchip() for KVM selftests - Factored-out ISA checks into separate sources - Added hideleg to struct kvm_vcpu_config - Factored-out VCPU config into separate sources - Support configuration of per-VM HGATP mode from KVM user space s390: - Support for ESA (31-bit) guests inside nested hypervisors. - Remove restriction on memslot alignment, which is not needed anymore with the new gmap code. - Fix LPSW/E to update the bear (which of course is the breaking event address register). x86: - Shut up various UBSAN warnings on reading module parameter before they were initialized. - Don't zero-allocate page tables that are used for splitting hugepages in the TDP MMU, as KVM is guaranteed to set all SPTEs in the page table and thus write all bytes. - As an optimization, bail early when trying to unsync 4KiB mappings if the target gfn can just be mapped with a 2MiB hugepage. x86 generic: - Copy single-chunk MMIO write values into struct kvm_vcpu (more precisely struct kvm_mmio_fragment) to fix use-after-free stack bugs where KVM would dereference stack pointer after an exit to userspace. - Clean up and comment the emulated MMIO code to try to make it easier to maintain (not necessarily "easy", but "easier"). - Move VMXON+VMXOFF and EFER.SVME toggling out of KVM (not *all* of VMX and SVM enabling) as it is needed for trusted I/O. - Advertise support for AVX512 Bit Matrix Multiply (BMM) instructions - Immediately fail the build if a required #define is missing in one of KVM's headers that is included multiple times. - Reject SET_GUEST_DEBUG with -EBUSY if there's an already injected exception, mostly to prevent syzkaller from abusing the uAPI to trigger WARNs, but also because it can help prevent userspace from unintentionally crashing the VM. - Exempt SMM from CPUID faulting on Intel, as per the spec. - Misc hardening and cleanup changes. x86 (AMD): - Fix and optimize IRQ window inhibit handling for AVIC; make it per-vCPU so that KVM doesn't prematurely re-enable AVIC if multiple vCPUs have to-be-injected IRQs. - Clean up and optimize the OSVW handling, avoiding a bug in which KVM would overwrite state when enabling virtualization on multiple CPUs in parallel. This should not be a problem because OSVW should usually be the same for all CPUs. - Drop a WARN in KVM_MEMORY_ENCRYPT_REG_REGION where KVM complains about a "too large" size based purely on user input. - Clean up and harden the pinning code for KVM_MEMORY_ENCRYPT_REG_REGION. - Disallow synchronizing a VMSA of an already-launched/encrypted vCPU, as doing so for an SNP guest will crash the host due to an RMP violation page fault. - Overhaul KVM's APIs for detecting SEV+ guests so that VM-scoped queries are required to hold kvm->lock, and enforce it by lockdep. Fix various bugs where sev_guest() was not ensured to be stable for the whole duration of a function or ioctl. - Convert a pile of kvm->lock SEV code to guard(). - Play nicer with userspace that does not enable KVM_CAP_EXCEPTION_PAYLOAD, for which KVM needs to set CR2 and DR6 as a response to ioctls such as KVM_GET_VCPU_EVENTS (even if the payload would end up in EXITINFO2 rather than CR2, for example). Only set CR2 and DR6 when consumption of the payload is imminent, but on the other hand force delivery of the payload in all paths where userspace retrieves CR2 or DR6. - Use vcpu->arch.cr2 when updating vmcb12's CR2 on nested #VMEXIT instead of vmcb02->save.cr2. The value is out of sync after a save/restore or after a #PF is injected into L2. - Fix a class of nSVM bugs where some fields written by the CPU are not synchronized from vmcb02 to cached vmcb12 after VMRUN, and so are not up-to-date when saved by KVM_GET_NESTED_STATE. - Fix a class of bugs where the ordering between KVM_SET_NESTED_STATE and KVM_SET_{S}REGS could cause vmcb02 to be incorrectly initialized after save+restore. - Add a variety of missing nSVM consistency checks. - Fix several bugs where KVM failed to correctly update VMCB fields on nested #VMEXIT. - Fix several bugs where KVM failed to correctly synthesize #UD or #GP for SVM-related instructions. - Add support for save+restore of virtualized LBRs (on SVM). - Refactor various helpers and macros to improve clarity and (hopefully) make the code easier to maintain. - Aggressively sanitize fields when copying from vmcb12, to guard against unintentionally allowing L1 to utilize yet-to-be-defined features. - Fix several bugs where KVM botched rAX legality checks when emulating SVM instructions. There are remaining issues in that KVM doesn't handle size prefix overrides for 64-bit guests. - Fail emulation of VMRUN/VMLOAD/VMSAVE if mapping vmcb12 fails instead of somewhat arbitrarily synthesizing #GP (i.e. don't double down on AMD's architectural but sketchy behavior of generating #GP for "unsupported" addresses). - Cache all used vmcb12 fields to further harden against TOCTOU bugs. x86 (Intel): - Drop obsolete branch hint prefixes from the VMX instruction macros. - Use ASM_INPUT_RM() in __vmcs_writel() to coerce clang into using a register input when appropriate. - Code cleanups. guest_memfd: - Don't mark guest_memfd folios as accessed, as guest_memfd doesn't support reclaim, the memory is unevictable, and there is no storage to write back to. LoongArch selftests: - Add KVM PMU test cases s390 selftests: - Enable more memory selftests. x86 selftests: - Add support for Hygon CPUs in KVM selftests. - Fix a bug in the MSR test where it would get false failures on AMD/Hygon CPUs with exactly one of RDPID or RDTSCP. - Add an MADV_COLLAPSE testcase for guest_memfd as a regression test for a bug where the kernel would attempt to collapse guest_memfd folios against KVM's will. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmnftRQUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroPAzwf+NKO4Ktv+7A22ImN0SBl0nlUuulsz vTcw3+hxdRoIw83GdNS+hG5js0wrpMDnbv3t4+VliDNBSSxrBzcSWX2wpilW0Xtw qGo1MWhs2lKPy1NlaRVOwPS6j7uF3AR0TQ1iQLGMedQuCU9WpiKJxyhNXJdbLrt3 8EgFzsvtEsv+jKNRUNDf9+d0j4gZsFyIe+Brhianbw+u3/UCiUClLCdsKPc4+5ZX 08otYXytacGNIf/5Ev1vT4pHkHL0yqKXAtX7LEtaS3+0KrPuLjV4slemivzE9vf5 Evafm5AhA4wpaNMb1ZerhY3T94lsMaJpWxotjR//0Q7C9B59pCQnXCm8mg== =CcE0 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "Arm: - Add support for tracing in the standalone EL2 hypervisor code, which should help both debugging and performance analysis.

soc: defconfig updates for 7.1

soc: drivers for 7.1
The driver updates again are all over the place with many minor fixes
going into platform specific code. The most notable changes are:
- Support for Microchip pic64gx system controllers
- Work on cleaning up devicetree bindings for SoC drivers, and
converting them into the new format
- Lots of smaller changes for Qualcomm SoC drivers, including support

soc: dt changes for 7.1
A number of SoC platforms are adding modernized variants of their
already supported chips time, with a total of 12 new SoCs,
and two older SoC getting removed:
- Qualcomm Glymur is a compute SoC using 18 Oryon-2 CPU cores
- Qualcomm Mahua is a variant of Glymur with only 12 CPU cores, but
largely identical.
- Qualcomm Eliza is an embeded platform for mobile phone (SM7750) and IOT
(QC7790S/M) workloads
- Qualcomm IPQ5210 is a wireless networking SoC using Cortex-A53 cores
- Qualcomm apq8084 and ipq806x had only rudimentary support but no
actual products using them, so they are now gone.
- Axis ARTPEC-9 is a follow-up to the ARTPEC-8 embedded SoC, using
the Samsung SoC platform but now with Cortex-A55 cores
- ARM Zena is a virtual platform in FVP using Cortex-A720AE cores, with
additional versions planned to be merged in the future.
- ARM corstone-1000-a320 is a reference platform for IOT, using low-end
Cortex-A320 cores
- Microchip LAN9691 is an updated 64-bit variant of the arm32 lan966x
series of networking SoCs
- Microchip PIC64GX is an embedded RISC-V chip using SIFIVE U54 CPU cores
- Rockchip RV1103B is the low-end 32-bit single-core vision processor
- Renesas RZ/G3L (r9a08g046) is an industrial embedded chip using
Cortex-A55 cores, similar to the G3E and G3S variants we already
supported.
- NXP S32N79 is an automotive SoC using Cortex-A78AE cores, a
significant upgrade from the older S32V and S32G series
These all come with at least one reference board or an initial product
using these, in total there are 67 newly added boards. The ones for
already supported SoCs are:
- Two more Aspeed BMC based boards
- Three older tablets based on 32-bit OMAP4 and Exynos5 SoCs
- One Set-top-box based on Allwinner H6
- 22 additional industrial/embedded boards using 64-bit NXP i.MX8M
or i.MX9 SoCs
- 20 Qualcomm SoC based machines across all possible markets:
workstation, gaming, laptop, phone, networking, reference, ...
- Three more Rockchips rk35xx based boards
- Four variants of the Toradex Verdin using TI AM62
Other notable bits are:
- A cleanup for the 32-bit Tegra paz00 board moved the last
board specific code on Tegra into equivalent dts syntax.
- There continues to be a significant number of fixes for static
checking of dtc syntax, but it feels like this is slowing down,
hopefully getting into a state where most known issues are
addressed
- Additional hardware support for many existing boards across SoC
families, notably Qualcomm, Broadcom, i.MX2, i.MX6, Rockchips,
STM32, Mediatek, Tegra, TI and Microchip

mm.git review status for linus..mm-nonmm-stable
Total patches: 126
Reviews/patch: 0.92
Reviewed rate: 76%
- The 2 patch series "pid: make sub-init creation retryable" from Oleg
Nesterov increases the robustness of our creation of init in a new
namespace. By clearing away some historical cruft which is no longer
needed. Also some documentation fixups are provided.
- The 2 patch series "selftests/fchmodat2: Error handling and general"
from Mark Brown has a fixup and a cleanup for the fchmodat2() syscall
selftest.
- The 3 patch series "lib: polynomial: Move to math/ and clean up" from
Andy Shevchenko does as advertised.
- The 3 patch series "hung_task: Provide runtime reset interface for
hung task detector" from Aaron Tomlin gives administrators the ability
to zero out /proc/sys/kernel/hung_task_detect_count.
- The 2 patch series "tools/getdelays: use the static UAPI headers from
tools/include/uapi" from Thomas Weißschuh teaches getdelays to use the
in-kernel UAPI headers rather than the system-provided ones.
- The 5 patch series "watchdog/hardlockup: Improvements to hardlockup"
from Mayank Rungta provides several cleanups and fixups to the
hardlockup detector code and its documentation.
- The 2 patch series "lib/bch: fix undefined behavior from signed
left-shifts" from Josh Law provides a couple of small/theoretical fixes
in the bch code.
- The 2 patch series "ocfs2/dlm: fix two bugs in dlm_match_regions()"
from Junrui Luo does what is claims.
- The 27 patch series "cleanup the RAID5 XOR library" from Christoph
Hellwig is a quite far-reaching cleanup to this code. I can't do better
than to quote Christoph:
The XOR library used for the RAID5 parity is a bit of a mess right
now. The main file sits in crypto/ despite not being cryptography and
not using the crypto API, with the generic implementations sitting in
include/asm-generic and the arch implementations sitting in an asm/
header in theory. The latter doesn't work for many cases, so
architectures often build the code directly into the core kernel, or
create another module for the architecture code.
Change this to a single module in lib/ that also contains the
architecture optimizations, similar to the library work Eric Biggers
has done for the CRC and crypto libraries later. After that it
changes to better calling conventions that allow for smarter
architecture implementations (although none is contained here yet),
and uses static_call to avoid indirection function call overhead.
- The 2 patch series "lib/list_sort: Clean up list_sort() scheduling
workarounds" from Kuan-Wei Chiu cleans up this library code by removing
a hacky thing which was added for UBIFS, which UBIFS doesn't actually
need.
- The 5 patch series "Fix bugs in extract_iter_to_sg()" from Christian
Ehrhardt fixes a few bugs in the scatterlist code, adds in-kernel tests
for the now-fixed bugs and fixes a leak in the test itself.
- The 3 patch series "kdump: Enable LUKS-encrypted dump target support
in ARM64 and PowerPC" from Coiby Xu eenables support of the
LUKS-encrypted device dump target on arm64 and powerpc.
- The 4 patch series "ocfs2: consolidate extent list validation into
block read callbacks" from Joseph Qi addresses ocfs2's validation of
extent list fields - cleanup, simplification, robustness. (Kernel test
robot loves mounting corrupted fs images!)
