Merge tag 'for-7.1/block-20260411' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull block updates from Jens Axboe:
- Add shared memory zero-copy I/O support for ublk, bypassing per-I/O
copies between kernel and userspace by matching registered buffer
PFNs at I/O time. Includes selftests.
- Refactor bio integrity to support filesystem initiated integrity
operations and arbitrary buffer alignment.
- Clean up bio allocation, splitting bio_alloc_bioset() into clear fast
and slow paths. Add bio_await() and bio_submit_or_kill() helpers,
unify synchronous bi_end_io callbacks.
- Fix zone write plug refcount handling and plug removal races. Add
support for serializing zone writes at QD=1 for rotational zoned
devices, yielding significant throughput improvements.
- Add SED-OPAL ioctls for Single User Mode management and a STACK_RESET
command.
- Add io_uring passthrough (uring_cmd) support to the BSG layer.
- Replace pp_buf in partition scanning with struct seq_buf.
- zloop improvements and cleanups.
- drbd genl cleanup, switching to pre_doit/post_doit.
- NVMe pull request via Keith:
- Fabrics authentication updates
- Enhanced block queue limits support
- Workqueue usage updates
- A new write zeroes device quirk
- Tagset cleanup fix for loop device
- MD pull requests via Yu Kuai:
- Fix raid5 soft lockup in retry_aligned_read()
- Fix raid10 deadlock with check operation and nowait requests
- Fix raid1 overlapping writes on writemostly disks
- Fix sysfs deadlock on array_state=clear
- Proactive RAID-5 parity building with llbitmap, with
write_zeroes_unmap optimization for initial sync
- Fix llbitmap barrier ordering, rdev skipping, and bitmap_ops
version mismatch fallback
- Fix bcache use-after-free and uninitialized closure
- Validate raid5 journal metadata payload size
- Various cleanups
- Various other fixes, improvements, and cleanups
