"This removes unused code of free space caching, disabled in 7.3
(commit 545e560a5b0f: "btrfs: disable v1 space cache").
It's been the original free space cache feature, superseded by free
space tree (4.5) and mkfs default since 5.15. The grace period was
sufficiently long, backward compatibility still exists with a
performance impact, effectively as if mounted with '-o nospace_cache'"

Pull ext4 updates from Ted Ts'o:
"Add support for buffered iomap support in ext4. This is not enabled by
default, but requires the buffered_iomap mount option, as this mode
does not support online defragmentation, inline data, fsverify,
fscrypt, non-extent inodes, and data=journal mode. If buffered_iomap
is enabled, ext4 will fall back to the original I/O code path
automatically if necessary. Large writes show significant performance
improvements when buffered iomap is enabled.
There are also miscellaneous bug fixes and improvements, including for
fast commit and avoiding deadlocks and out-of-bound reads when
handling corner cases involving corrupted file systems"

"New features:
- Implement ioctls to list, read, write, and remove named streams on

through streams_interface=windows, exposing streams as regular file
descriptors with support for mmap, locking, truncation, and
allocation.
- Support file attribute queries and updates through FS_IOC_GETFLAGS

noatime settings in the private $LINUXFLAGS extended attribute and
restore them when loading inodes. Also report compression,
encryption, and the mount-wide case-folding policy as read-only

Pull exfat updates from Namjae Jeon:
- Use the recalculated append position when advancing valid_size, dirty
all pages involved in valid-data extension, and zero invalid tails on
partial overwrites. Write-protect the folio spanning the old EOF and
zero its post-EOF range when extending a file, ensuring subsequent
mmap writes advance valid_size.
- Make valid_size and zeroed_size atomic to prevent torn reads and lost
updates. Hold the invalidate lock during truncation, and drain
in-flight direct I/O before buffered writes, buffered fallback, and
page-cache operations that extend valid_size.
- Fall back to single-cluster allocation when a buffered write cannot
allocate its entire range, allowing writes to consume the remaining
free space and return a short count.

"Jeff Layton extended the netlink listener-set operation so that
a management daemon can register NFSD's programs with rpcbind
itself. This prevents an unresponsive rpcbind from stalling NFSD
administration for a minute at a time.
Bulk delegation recall now adjusts the number of delegations it
wants returned, based on memory pressure. The previous mechanism
was spec-conformant, but it requested all delegations to be
returned at once. Clients are free to return few or none in such
cases, but requesting smaller batches of delegations is more
neighborly.
In preparation for handling TLS KeyUpdate, the server's TCP
receive path has been reworked to handle control records. In the
process, the use of sock_recvmsg was replaced with ->read_sock,
which contends less with other holders of the socket lock.

Pull firewire updates from Takashi Sakamoto:
- Guarantee asynchronous packet and transaction callbacks in process
context
Both the 1394 OHCI driver and the core transaction layer have been
changed to guarantee that asynchronous packet and transaction
callbacks are invoked in process context. In v6.17, the execution
context depended on the transaction destination: callbacks for
transactions destined for remote nodes were invoked from a workqueue,
whereas callbacks for transactions destined for the local node or
terminated due to internal errors were invoked in the transaction
initiator's context.
All such callbacks are now guaranteed to execute in process context,
eliminating the need to account for different execution contexts when
implementing callback functions.
