The recent move of the bdev_statx call to the low-level vfs_getattr_nosec
helper caused it being used by devtmpfs, which leads to deadlocks in
md teardown due to the block device lookup and put interfering with the
unusual lifetime rules in md.
But as handle_remove only works on inodes created and owned by devtmpfs
itself there is no need to use vfs_getattr_nosec vs simply reading the
mode from the inode directly. Switch to that to avoid the bdev lookup
or any other unintentional side effect.

Introduce a heartbeat-based Timeout Detection and Recovery (TDR) mechanism.
The enhancement aims to improve the reliability of device hang detection by
monitoring heartbeat updates.
Each progressing inference will update heartbeat counter allowing driver to
monitor its progression. Limit maximum number of reschedules when heartbeat
indicates progression to 30. This increases the maximum running time of
single inference to about 60 seconds.
The heartbeat mechanism provides a more robust method for detecting device
hangs, potentially reducing false positive recoveries due to long running
inferences.

After recent changes in the VM network stack, the host fails to
display the IP addresses of the VM. As a result the "IP Addresses"
column in the "Networking" tab in the Windows Hyper-V Manager is
empty. This is caused by a change in the expected output of the
"ip route show" command. Previously the gateway address was shown
in the third row. Now the gateway addresses might be split into
several lines of output. As a result, the string "ra" instead of
an IP address is sent to the host.
To me more specific, a VM with the wellknown wicked network

Previously the offload of the rule with header rewrite and mirror to
both internal and external destinations is skipped if the encap entry
is not valid. But it shouldn't because driver will try to offload it
again if neighbor is updated and encap entry is valid, to replace the
old FTE added for slow path. But the extra split attr doesn't exist at
that time as the process is skipped, driver then fails to offload it.
To fix this issue, remove the checking and continue the attr process
if encap entry is invalid.

Move rx_lock from xsk_socket to xsk_buff_pool.
Fix synchronization for shared umem mode in
generic RX path where multiple sockets share
single xsk_buff_pool.
RX queue is exclusive to xsk_socket, while FILL
queue can be shared between multiple sockets.
This could result in race condition where two
CPU cores access RX path of two different sockets
sharing the same umem.
Protect both queues by acquiring spinlock in shared
xsk_buff_pool.
Lock contention may be minimized in the future by some
per-thread FQ buffering.
It's safe and necessary to move spin_lock_bh(rx_lock)
after xsk_rcv_check():
* xs->pool and spinlock_init is synchronized by
xsk_bind() -> xsk_is_bound() memory barriers.
* xsk_rcv_check() may return true at the moment
of xsk_release() or xsk_unbind_dev(),
however this will not cause any data races or
race conditions. xsk_unbind_dev() removes xdp
socket from all maps and waits for completion
of all outstanding rx operations. Packets in
RX path will either complete safely or drop.

bcachefs currently populates fiemap data from the extents btree.
This works correctly when the fiemap sync flag is provided, but if
not, it skips all delalloc extents that have not yet been flushed.
This is because delalloc extents from buffered writes are first
stored as reservation in the pagecache, and only become resident in
the extents btree after writeback completes.
Update the fiemap implementation to process holes between extents by
scanning pagecache for data, via seek data/hole. If a valid data
range is found over a hole in the extent btree, fake up an extent
key and flag the extent as delalloc for reporting to userspace.
Note that this does not necessarily change behavior for the case
where there is dirty pagecache over already written extents, where
when in COW mode, writeback will allocate new blocks for the
underlying ranges. The existing behavior is consistent with btrfs
and it is recommended to use the sync flag for the most up to date
extent state from fiemap.

The bulk of the loop in bch2_fiemap() involves processing the
current extent key from the iter, including following indirections
and trimming the extent size and such. This patch makes a few
changes to reduce the size of the loop and facilitate future changes
to support delalloc extents.
Define a new bch_fiemap_extent structure to wrap the bkey buffer
that holds the extent key to report to userspace along with
associated fiemap flags. Update bch2_fill_extent() to take the
bch_fiemap_extent as a param instead of the individual fields.
Finally, lift the bulk of the extent processing into a
bch2_fiemap_extent() helper that takes the current key and formats
the bch_fiemap_extent appropriately for the fill function.
No functional changes intended by this patch.

The issue this assert is guarding against is that in
BTREE_ITER_filter_snapshots mode we only want to be iterating within a
single inode number - if we iterate into another inode number with keys
for a different snapshot tree, we'll loop arbitrarily long before

insn_decoder_test found a problem with decoding APX CTEST instructions:
Found an x86 instruction decoder bug, please report this.
ffffffff810021df 62 54 94 05 85 ff ctestneq
objdump says 6 bytes, but insn_get_length() says 5
It happens because x86-opcode-map.txt doesn't specify arguments for the
instruction and the decoder doesn't expect to see ModRM byte.

Perf doesn't work at perf stat for hardware events on certain x86 platforms:
$perf stat -- sleep 1
Performance counter stats for 'sleep 1':
16.44 msec task-clock # 0.016 CPUs utilized
2 context-switches # 121.691 /sec
0 cpu-migrations # 0.000 /sec
54 page-faults # 3.286 K/sec
<not supported> cycles
<not supported> instructions
<not supported> branches
<not supported> branch-misses
The reason is that the check in x86_pmu_hw_config() for sampling events is
unexpectedly applied to counting events as well.
It should only impact x86 platforms with limit_period used for non-PEBS
events. For Intel platforms, it should only impact some older platforms,
e.g., HSW, BDW and NHM.

When a VNI is deleted from a VXLAN device in 'vnifilter' mode, the FDB
entry associated with the default remote (assuming one was configured)
is deleted without holding the hash lock. This is wrong and will result
in a warning [1] being generated by the lockdep annotation that was
added by commit ebe6420674 ("vxlan: Create wrappers for FDB lookup").
Reproducer:
# ip link add vx0 up type vxlan dstport 4789 external vnifilter local 192.0.2.1
# bridge vni add vni 10010 remote 198.51.100.1 dev vx0
# bridge vni del vni 10010 dev vx0
Fix by acquiring the hash lock before the deletion and releasing it
afterwards. Blame the original commit that introduced the issue rather
than the one that exposed it.

When memory allocation profiling is disabled at runtime or due to an
error, shutdown_mem_profiling() is called: slab->obj_exts which
previously allocated remains.
It won't be cleared by unaccount_slab() because of
mem_alloc_profiling_enabled() not true. It's incorrect, slab->obj_exts
should always be cleaned up in unaccount_slab() to avoid following error:
[...]BUG: Bad page state in process...
..
[...]page dumped because: page still charged to cgroup

A previous commit added a 'sync' parameter to io_fallback_tw(), which if
true, means the caller wants to wait on the fallback thread handling it.
But the logic is somewhat messed up, ensure that ctxs are swapped and

The GNU coreutils version of truncate, which is the original, accepts a
% prefix for the -s size argument which means the file in question
should be padded to a multiple of the given size. This is currently used
to pad the setup block of bzImage to a multiple of 4k before appending
the decompressor.
busybox reimplements truncate but does not support this idiom, and
therefore fails the build since commit
9c54baab44 ("x86/boot: Drop CRC-32 checksum and the build tool that generates it")
Since very little build code within the kernel depends on the 'truncate'
utility, work around this incompatibility by avoiding truncate altogether,
and relying on dd to perform the padding.
