We use add_root_meta_rsv and sub_root_meta_rsv to track prealloc and
pertrans reservations for subvolumes when quotas are enabled. The
convert function does not properly increment pertrans after decrementing
prealloc, so the count is not accurate.
Note: we check that the fs is not read-only to mirror the logic in
qgroup_convert_meta, which checks that before adding to the pertrans rsv.

Sometimes the readout of /sys/kernel/debug/swiotlb/io_tlb_used and
io_tlb_used_hiwater can be a huge number (e.g. 18446744073709551615),
which is actually a negative number if we use "%ld" to print the number.
When swiotlb_create_default_debugfs() is running from late_initcall,
mem->total_used may already be non-zero, because the storage driver
may have already started to perform I/O operations: if the storage
driver is built-in, its probe() callback is called before late_initcall.
swiotlb_create_debugfs_files() should not blindly set mem->total_used
and mem->used_hiwater to 0; actually it doesn't have to initialize the
fields at all, because the fields, as part of the global struct
io_tlb_default_mem, have been implicitly initialized to zero.
Also don't explicitly set mem->transient_nslabs to 0.

In current code, swiotlb_bounce() may do partial sync's correctly in
some circumstances, but may incorrectly fail in other circumstances.
The failure cases require both of these to be true:
1) swiotlb_align_offset() returns a non-zero "offset" value
2) the tlb_addr of the partial sync area points into the first
"offset" bytes of the _second_ or subsequent swiotlb slot allocated
for the mapping
Code added in commit 868c9ddc18 ("swiotlb: add overflow checks
to swiotlb_bounce") attempts to WARN on the invalid case where
tlb_addr points into the first "offset" bytes of the _first_
allocated slot. But there's no way for swiotlb_bounce() to distinguish
the first slot from the second and subsequent slots, so the WARN
can be triggered incorrectly when #2 above is true.
Related, current code calculates an adjustment to the orig_addr stored
in the swiotlb slot. The adjustment compensates for the difference
in the tlb_addr used for the partial sync vs. the tlb_addr for the full
mapping. The adjustment is stored in the local variable tlb_offset.
But when #1 and #2 above are true, it's valid for this adjustment to
be negative. In such case the arithmetic to adjust orig_addr produces
the wrong result due to tlb_offset being declared as unsigned.
Fix these problems by removing the over-constraining validations added
in 868c9ddc18. Change the declaration of tlb_offset to be signed
instead of unsigned so the adjustment arithmetic works correctly.
Tested with a test-only hack to how swiotlb_tbl_map_single() calls
swiotlb_bounce(). Instead of calling swiotlb_bounce() just once
for the entire mapped area, do a loop with each iteration doing
only a 128 byte partial sync until the entire mapped area is
sync'ed. Then with swiotlb=force on the kernel boot line, run a
variety of raw disk writes followed by read and verification of
all bytes of the written data. The storage device has DMA
min_align_mask set, and the writes are done with a variety of
original buffer memory address alignments and overall buffer
sizes. For many of the combinations, current code triggers the
WARN statements, or the data verification fails. With the fixes,
no WARNs occur and all verifications pass.

Allow a buffer pre-padding of up to alloc_align_mask, even if it requires
allocating additional IO TLB slots.
If the allocation alignment is bigger than IO_TLB_SIZE and min_align_mask
covers any non-zero bits in the original address between IO_TLB_SIZE and
alloc_align_mask, these bits are not preserved in the swiotlb buffer
address.
To fix this case, increase the allocation size and use a larger offset
within the allocated buffer. As a result, extra padding slots may be
allocated before the mapping start address.
Leave orig_addr in these padding slots initialized to INVALID_PHYS_ADDR.
These slots do not correspond to any CPU buffer, so attempts to sync the
data should be ignored.
The padding slots should be automatically released when the buffer is
unmapped. However, swiotlb_tbl_unmap_single() takes only the address of the
DMA buffer slot, not the first padding slot. Save the number of padding
slots in struct io_tlb_slot and use it to adjust the slot index in
swiotlb_release_slots(), so all allocated slots are properly freed.

Linux 6.9 made the nvme multipath nodes not properly pick up changes when
the LBA size goes smaller after an nvme format. This is because we now
try to inherit the queue settings for the multipath node entirely from
the individual paths. That is the right thing to do for I/O size
limitations, which make up most of the queue limits, but it is wrong for
changes to the namespace configuration, where we do want to pick up the
new format, which will eventually show up on all paths once they are
re-queried.
Fix this by not inheriting the block size and related fields and always
for updating them.

syzkaller started using corpuses where a BPF tracing program deletes
elements from a sockmap/sockhash map. Because BPF tracing programs can be
invoked from any interrupt context, locks taken during a map_delete_elem
operation must be hardirq-safe. Otherwise a deadlock due to lock inversion
is possible, as reported by lockdep:
CPU0 CPU1
---- ----
lock(&htab->buckets[i].lock);
local_irq_disable();
lock(&host->lock);
lock(&htab->buckets[i].lock);
<Interrupt>
lock(&host->lock);
Locks in sockmap are hardirq-unsafe by design. We expects elements to be
deleted from sockmap/sockhash only in task (normal) context with interrupts
enabled, or in softirq context.
Detect when map_delete_elem operation is invoked from a context which is
_not_ hardirq-unsafe, that is interrupts are disabled, and bail out with an
error.
Note that map updates are not affected by this issue. BPF verifier does not
allow updating sockmap/sockhash from a BPF tracing program today.

This patch addresses an issue with the Panasonic CF-SZ6's existing quirk,
specifically its headset microphone functionality. Previously, the quirk
used ALC269_FIXUP_HEADSET_MODE, which does not support the CF-SZ6's design
of a single 3.5mm jack for both mic and audio output effectively. The
device uses pin 0x19 for the headset mic without jack detection.
Following verification on the CF-SZ6 and discussions with the original
patch author, i determined that the update to
ALC269_FIXUP_ASPIRE_HEADSET_MIC is the appropriate solution. This change
is custom-designed for the CF-SZ6's unique hardware setup, which includes
a single 3.5mm jack for both mic and audio output, connecting the headset
microphone to pin 0x19 without the use of jack detection.

As already anticipated in the original commit, playback was broken for
very short samples. I just didn't expect it to be an actual problem,
because we're talking about less than 1.5 milliseconds here. But clearly
such wavetable samples do actually exist.
The problem was that for such short samples we'd set the current
position beyond the end of the loop, so we'd run off the end of the
sample and play garbage.
This is a bigger (more audible) problem than the original one, which was
that we'd start playback with garbage (whatever was still in the cache),
which would be mostly masked by the note's attack phase.
So revert to the old behavior for now. We'll subsequently fix it
properly with a bigger patch series.
Note that this isn't a full revert - the dead code is not re-introduced,
because that would be silly.

Probably due to a firmware bug Dell TB16 dock announces that one of its
DisplayPort adapters is actually DP IN. Now this is possible and used
with some external GPUs but not likely in this case as we are dealing
with a dock. Anyways the problem is that the driver tries to create a
DisplayPort tunnel between adapters of the same router which then shows
to user that there is no picture on the display (because there are no
available DP OUT adapters on the dock anymore).
Fix this by not creating DisplayPort tunnels between adapters that are
on the same router.

Commit 73d9629e1c ("i40e: Do not allow untrusted VF to remove
administratively set MAC") fixed an issue where untrusted VF was
allowed to remove its own MAC address although this was assigned
administratively from PF. Unfortunately the introduced check
is wrong because it causes that MAC filters for other MAC addresses
including multi-cast ones are not removed.
<snip>
if (ether_addr_equal(addr, vf->default_lan_addr.addr) &&
i40e_can_vf_change_mac(vf))
was_unimac_deleted = true;
else
continue;
if (i40e_del_mac_filter(vsi, al->list[i].addr)) {
...
</snip>
The else path with `continue` effectively skips any MAC filter
removal except one for primary MAC addr when VF is allowed to do so.
Fix the check condition so the `continue` is only done for primary
MAC address.

Matthieu Baerts says:
====================
mptcp: fix fallback MIB counter and wrong var in selftests
Here are two fixes related to MPTCP.
The first patch fixes when the MPTcpExtMPCapableFallbackACK MIB counter
is modified: it should only be incremented when a connection was using
MPTCP options, but then a fallback to TCP has been done. This patch also
checks the counter is not incremented by mistake during the connect
selftests. This counter was wrongly incremented since its introduction
in v5.7.
The second patch fixes a wrong parsing of the 'dev' endpoint options in
the selftests: the wrong variable was used. This option was not used
before, but it is going to be soon. This issue is visible since v5.18.
