Removing a free space entry from an in memory space cache requires having
the corresponding btrfs_free_space_ctl's 'tree_lock' held. We have several
code paths that remove an entry, so add assertions where appropriate to
verify we are holding the lock, as the lock is acquired by some other
function up in the call chain, which makes it easy to miss in the future.
Note: for this to work we need to lock the local btrfs_free_space_ctl at
load_free_space_cache(), which was not being done because it's local,
declared on the stack, so no other task has access to it.

When linking a free space entry, at link_free_space(), the caller should
be holding the spinlock 'tree_lock' of the given btrfs_free_space_ctl
argument, which is necessary for manipulating the red black tree of free
space entries (done by tree_insert_offset(), which already asserts the
lock is held) and for manipulating the 'free_space', 'free_extents',
'discardable_extents' and 'discardable_bytes' counters of the given
struct btrfs_free_space_ctl.
So assert that the spinlock 'tree_lock' of the given btrfs_free_space_ctl
is held by the current task. We have multiple code paths that end up
calling link_free_space(), and all currently take the lock before calling
it.

When searching for a free space entry by offset, at tree_search_offset(),
we are supposed to have the btrfs_free_space_ctl's 'tree_lock' held, so
assert that. We have multiple callers of tree_search_offset(), and all
currently hold the necessary lock before calling it.

There are multiple code paths leading to tree_insert_offset(), and each
path takes the necessary locks before tree_insert_offset() is called,
since they do other things that require those locks to be held. This makes
it easy to miss the locking somewhere, so make tree_insert_offset() assert
that the required locks are being held by the calling task.

For the in-memory component of space caching (free space cache and free
space tree), three of the arguments passed to tree_insert_offset() can
always be taken from the new free space entry that we are about to add.
So simplify tree_insert_offset() to take the new entry instead of the
'offset', 'node' and 'bitmap' arguments. This will also allow to make
further changes simpler.

At copy_free_space_cache(), we add a new entry to the block group's ctl
before we free the entry from the temporary ctl. Adding a new entry
requires the allocation of a new struct btrfs_free_space, so we can
avoid a temporary extra allocation by freeing the entry from the
temporary ctl before we add a new entry to the main ctl, which possibly
also reduces the chances for a memory allocation failure in case of very
high memory pressure. So just do that.

[PROBLEM]
When relocation fails (mostly due to checksum mismatch), we only got
very cryptic error messages like:
BTRFS info (device dm-4): relocating block group 13631488 flags data
BTRFS warning (device dm-4): csum failed root -9 ino 257 off 0 csum 0x373e1ae3 expected csum 0x98757625 mirror 1
BTRFS error (device dm-4): bdev /dev/mapper/test-scratch1 errs: wr 0, rd 0, flush 0, corrupt 1, gen 0
BTRFS info (device dm-4): balance: ended with status: -5
The end user has to decipher the above messages and use various tools to
locate the affected files and find a way to fix the problem (mostly
deleting the file). This is not an easy work even for experienced
developer, not to mention the end users.
[SCRUB IS DOING BETTER]
By contrast, scrub is providing much better error messages:
BTRFS error (device dm-4): unable to fixup (regular) error at logical 13631488 on dev /dev/mapper/test-scratch1 physical 13631488
BTRFS warning (device dm-4): checksum error at logical 13631488 on dev /dev/mapper/test-scratch1, physical 13631488, root 5, inode 257, offset 0, length 4096, links 1 (path: file)
BTRFS info (device dm-4): scrub: finished on devid 1 with status: 0
Which provides the affected files directly to the end user.
[IMPROVEMENT]
Instead of the generic data checksum error messages, which is not doing
a good job for data reloc inodes, this patch introduce a scrub like
backref walking based solution.
When a sector fails its checksum for data reloc inode, we go the
following workflow:
- Get the real logical bytenr
For data reloc inode, the file offset is the offset inside the block
group.
Thus the real logical bytenr is @file_off + @block_group->start.
- Do an extent type check
If it's tree blocks it's much easier to handle, just go through
all the tree block backref.
- Do a backref walk and inode path resolution for data extents
This is mostly the same as scrub.
But unfortunately we can not reuse the same function as the output
format is different.
Now the new output would be more user friendly:
BTRFS info (device dm-4): relocating block group 13631488 flags data
BTRFS warning (device dm-4): csum failed root -9 ino 257 off 0 logical 13631488 csum 0x373e1ae3 expected csum 0x98757625 mirror 1
BTRFS warning (device dm-4): checksum error at logical 13631488 mirror 1 root 5 inode 257 offset 0 length 4096 links 1 (path: file)
BTRFS error (device dm-4): bdev /dev/mapper/test-scratch1 errs: wr 0, rd 0, flush 0, corrupt 2, gen 0
BTRFS info (device dm-4): balance: ended with status: -5

The writeback_control structure already passes down the information about
a writeback being synchronous from the core VM code, and thus information
is propagated into the bio REQ_SYNC flag through the wbc_to_write_flags
helper.
Use that information to decide if checksums calculation is offloaded to
a workqueue instead of btrfs_inode::sync_writers field that not only
bloats the inode but also has too wide scope, being inode wide instead
of limited to the actual writeback request.
The sync writes were set in:
- btrfs_do_write_iter - regular IO, sync status is set
- start_ordered_ops - ordered write start, writeback with WB_SYNC_ALL
mode
- btrfs_write_marked_extents - write marked extents, writeback with
WB_SYNC_ALL mode

Most modern hardware supports very fast accelerated crc32c calculation.
If that is supported the CPU overhead of the checksum calculation is
very limited, and offloading the calculation to special worker threads
has a lot of overhead for no gain.
E.g. on an Intel Optane device is actually very much slows down even
1M buffered writes with fio:
Unpatched:
write: IOPS=3316, BW=3316MiB/s (3477MB/s)(200GiB/61757msec); 0 zone resets
With synchronous CRCs:
write: IOPS=4882, BW=4882MiB/s (5119MB/s)(200GiB/41948msec); 0 zone resets
With a lot of variation during the unpatched run going down as low as
1100MB/s, while the synchronous CRC version has about the same peak write
speed but much lower dips, and fewer kworkers churning around.
Both tests had fio saturated at 100% CPU.
(thanks to Jens Axboe via Chris Mason for the benchmarking)

When checking siblings keys, before moving keys from one node/leaf to a
sibling node/leaf, it's very unexpected to have the last key of the left
sibling greater than or equals to the first key of the right sibling, as
that means we have a (serious) corruption that breaks the key ordering
properties of a b+tree. Since this is unexpected, surround the comparison
with the unlikely macro, which helps the compiler generate better code
for the most expected case (no existing b+tree corruption). This is also
what we do for other unexpected cases of invalid key ordering (like at
btrfs_set_item_key_safe()).

Recently a Meta-internal workload encountered subvolume creation taking
up to 2s each, significantly slower than directory creation. As they
were hoping to be able to use subvolumes instead of directories, and
were looking to create hundreds, this was a significant issue. After
Josef investigated, it turned out to be due to the transaction commit
currently performed at the end of subvolume creation.
This change improves the workload by not doing transaction commit for every
subvolume creation, and merely requiring a transaction commit on fsync.
In the worst case, of doing a subvolume create and fsync in a loop, this
should require an equal amount of time to the current scheme; and in the
best case, the internal workload creating hundreds of subvolumes before
fsyncing is greatly improved.
While it would be nice to be able to use the log tree and use the normal
fsync path, log tree replay can't deal with new subvolume inodes
presently.
It's possible that there's some reason that the transaction commit is
necessary for correctness during subvolume creation; however,
git logs indicate that the commit dates back to the beginning of
subvolume creation, and there are no notes on why it would be necessary.

When an ATA port is resumed from sleep, the port is reset and a power
management request issued to libata EH to reset the port and rescanning
the device(s) attached to the port. Device rescanning is done by
scheduling an ata_scsi_dev_rescan() work, which will execute
scsi_rescan_device().
However, scsi_rescan_device() takes the generic device lock, which is
also taken by dpm_resume() when the SCSI device is resumed as well. If
a device rescan execution starts before the completion of the SCSI
device resume, the rcu locking used to refresh the cached VPD pages of
the device, combined with the generic device locking from
scsi_rescan_device() and from dpm_resume() can cause a deadlock.
Avoid this situation by changing struct ata_port scsi_rescan_task to be
a delayed work instead of a simple work_struct. ata_scsi_dev_rescan() is
modified to check if the SCSI device associated with the ATA device that
must be rescanned is not suspended. If the SCSI device is still
suspended, ata_scsi_dev_rescan() returns early and reschedule itself for
execution after an arbitrary delay of 5ms.

The fix simply adds the initialization, but introduces a #ifdef

Yes, it would be nice to abstract this somehow in order to hide it in
SRCU, but I still don't see a good way of doing this"

another stopping us seeing spurious failures setting the master volume
on some Tegra systems introduced by a change to how we calculate delay

This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for
HEM devices which supports native DSD. Prior to this change Linux kernel
was not enabling native DSD playback for HEM devices, and as a result,
DSD audio was being converted to PCM "on the fly". HEM devices,
when connected to the system, would only play audio in PCM format,
even if the source material was in DSD format. With the addition of new
VENDOR_FLG in the quircks.c file, the devices are now correctly
recognized, and raw DSD data is transmitted to the device,
allowing for native DSD playback.

As reported in the bugzilla below, the PM resume of a UAC3 device may
fail due to the incomplete power state change, stuck at D1. The
reason is that the driver expects the full D0 power state change only
at hw_params, while the normal PCM resume procedure doesn't call
hw_params.
For fixing the bug, we add the same power state update to D0 at the
prepare callback, which is certainly called by the resume procedure.
Note that, with this change, the power state change in the hw_params
becomes almost redundant, since snd_usb_hw_params() doesn't touch the
parameters (at least it tires so). But dropping it is still a bit
risky (e.g. we have the media-driver binding), so I leave the D0 power
state change in snd_usb_hw_params() as is for now.

Although snd_seq_oss_midi_open() and snd_seq_oss_midi_close() can be
called concurrently from different code paths, we have no proper data
protection against races. Introduce open_mutex to each seq_oss_midi
object for avoiding the races.

Pull networking fixes from Jakub Kicinski:
"Including fixes from wireless, and netfilter.
Selftests excluded - we have 58 patches and diff of +442/-199, which
isn't really small but perhaps with the exception of the WiFi locking
change it's old(ish) bugs.
We have no known problems with v6.4.
The selftest changes are rather large as MPTCP folks try to apply
Greg's guidance that selftest from torvalds/linux should be able to
run against stable kernels.
Last thing I should call out is the DCCP/UDP-lite deprecation notices.
We are fairly sure those are dead, but if we're wrong reverting them
back in won't be fun.

Pull rdma fixes from Jason Gunthorpe:
"This is an unusually large bunch of bug fixes for the later rc cycle,
rxe and mlx5 both dumped a lot of things at once. rxe continues to fix
itself, and mlx5 is fixing a bunch of "queue counters" related bugs.
There is one highly notable bug fix regarding the qkey. This small
security check was missed in the original 2005 implementation and it
allows some significant issues.
Summary:
- Two rtrs bug fixes for error unwind bugs
- Several rxe bug fixes:
* Incorrect Rx packet validation
* Using memory without a refcount
* Syzkaller found use before initialization
* Regression fix for missing locking with the tasklet conversion
from this merge window
- Have bnxt report the correct link properties to userspace, this was
a regression in v6.3
- Several mlx5 bug fixes:
* Kernel crash triggerable by userspace for the RAW ethernet
profile
* Defend against steering refcounting issues created by userspace
* Incorrect change of QP port affinity parameters in some LAG
configurations
- Fix mlx5 Q counters:
* Do not over allocate Q counters to allow userspace to use the
full port capacity
* Kernel crash triggered by eswitch due to mis-use of Q counters
* Incorrect mlx5_device for Q counters in some LAG configurations
- Properly implement the IBA spec restricting privileged qkeys to
root
- Always an error when reading from a disassociated device's event
queue
- isert bug fixes:
* Avoid a deadlock with the CM handler and CM ID destruction
* Correct list corruption due to incorrect locking
* Fix a use after free around connection tear down"
