Pull block updates from Jens Axboe:
- NVMe updates via Keith:
- Apple M4 (t8132) ANS2 NVMe support
- nvme-multipath sysfs attributes for path_state, iopolicies, and
fail_on_ctrl_loss, plus path state evaluation fixes
- nvme-tcp parallelized I/O queue allocation and startup, and using
the caller's network namespace
- nvmet passthru UAF fix and rework, PR preempt use-after-free
fixes, auth hardening, and traffic based keep alive support
- DH-HMAC-CHAP secret attributes readable by root only
- Various other fixes and cleanups
- swim driver overhaul and fixes, plus floppy fixes, via a pull from
Denis
- Block device buffered and direct I/O rework from Tal: use
iomap_dirty_folio, take i_rwsem for the write fallback and splice
read, honor IOCB_NOWAIT in the buffered read path, and reject atomic
write fallback to buffered I/O
- Large zone revalidation rework: serialize revalidation, handle
capacity changes by dropping and retrying zone write plugs, propagate
read-only and offline conditions, and treat offline and read-only
zones as dead
- ublk robustness work around canceled FETCH rounds and going live over
canceled io commands, dropping the default I/O scheduler, and a batch
of selftest additions
- blk-iocost flush cost support and zone append accounting
- rust block fixes for Send/Sync bounds on GenDisk and TagSet, and
import style cleanups
- Atomic write fixes capping size by the PI buffer constraints and
failing short atomic pins
- Skip the redundant flush for O_DSYNC direct writes, and only use
REQ_FUA when the device supports it
- Store GPT attributes as a raw value
- Remove support for swapping loop fds
- Various other fixes and cleanups all over
