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
