Merge tag 'for-7.3/block-20260819' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull block updates from Jens Axboe:

- NVMe updates via Keith:
- Enable Clang context analysis for the nvme host driver, adding
context annotations across core, fabrics, rdma, tcp and pci
- nvmet reservation state exposed through a new namespace-level
debugfs directory, plus ABI documentation for the host sysfs and
target configfs interfaces
- nvme-tcp host memory disclosure fixes on the read path: reject a
read that transferred too few bytes, don't accept C2HData based
on blk_rq_payload_bytes() alone, and fix the R2T case for a read
command
- Parallelize nvme-rdma I/O queue allocation and startup (Surabhi)
- Apple nvme fixes and quirks: page aligned admin queue buffers,
destroy the admin queue on removal, and various DMA/NVMMU
correctness fixes
- A large pile of nvmet and host fixes for out-of-bounds reads,
refcount/resource leaks, and NULL derefs across auth, zns,
passthru, pci-epf, rdma and configfs
- Various other fixes and cleanups

- MD updates via Yu Kuai:
- llbitmap reshape support, the large series wiring exact bitmap
mapping and reshape lifecycle through raid5 and raid10, growing
the page cache in place, and remapping checkpointed bits as
reshape progresses
- raid5 fixes for lockless max_nr_stripes and recovery_offset
accesses, a reshape deadlock with more failed devices than max
degraded, and bitmap batch counter consistency
- Atomic write handling for raid1/raid10, and removal of the
REQ_NOWAIT support from raid1/10/456
- raid5-ppl use-after-free fix in ppl_do_flush()
- A batch of smaller fixes across md core and the bitmap code

- s390/dasd ESE full-track write support and the surrounding
infrastructure, plus enabling CONTEXT_ANALYSIS for s390/block

- RWF_DONTCACHE support for block devices, built on new task-context
bio completion infrastructure, and wiring it up for the iomap and
buffer dropbehind writeback paths

- Async io_uring zone reset all, plus zone management command cleanups
allowing REQ_NOWAIT and tightening conventional zone rejection

- Block integrity refactoring: lift BIP_CHECK_FLAGS to the shared
header, handle nogenerate/noverify properly in fs-integrity, and drop
the blk-integrity.h include from bdev.c

- Split out a new blk_plug.h header

- ublk improvements: add UBLK_F_IO_DESC_SIZE, split request validation
from io_desc init, reject non-power-of-2 zone sizes in SET_PARAMS,
and a series of hardening fixes around map/unmap and auto buf reg

- null_blk cleanups and configfs serialization fixes

- nbd queue freeze removal on the setup paths, and a new
pre_defined_connections module parameter for pre-created devices

- blk-cgroup fixes for the race between policy activation and blkg
destruction, and accounting per-cpu stats over possible CPUs across
blk-stat, iolatency, iocost and kyber

- Various dio fixes: leak on metadata mapping error, validate user
space vectors during extraction, and set dma_alignment from the
backing file for loop and zloop direct I/O

- bio cleanups

- Various other fixes and cleanups all over

selftests: ublk: add SET_PARAMS validation test

Add test_params_01.sh for SET_PARAMS. The test checks valid basic
parameters and several invalid parameter cases.

Also cover zoned parameters, including a non-power-of-2 zone size. This
case must fail in SET_PARAMS instead of being accepted and rejected later
when the device is started.
