Merge tag 'block-7.2-20260625' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull block fixes from Jens Axboe:

 - blk-cgroup locking rework and fixes:
      - fix a use-after-free in __blkcg_rstat_flush()
      - defer freeing policy data until after an RCU grace period
      - defer the blkcg css_put until the blkg is unlinked from
        the queue
      - unwind the queue_lock nesting under RCU / blkcg->lock
        across the lookup, create, associate and destroy paths

 - NVMe fixes via Keith:
      - Fix a crash and memory leak during invalid cdev teardown,
        and related cdev cleanups (Maurizio, John)
      - nvmet fixes: handle TCP_CLOSING in the tcp state_change
        handler, reject short AUTH_RECEIVE buffers, handle inline
        data with a nonzero offset in rdma, fix an sq refcount leak,
        and allocate ana_state with the port (Maurizio, Michael,
        Bryam, Wentao, Rosen)
      - nvme-fc fix to not cancel requests on an IO target before it
        is initialized (Mohamed)
      - nvme-apple fix to prevent shared tags across queues on Apple
        A11 (Nick)
      - Various smaller fixes and cleanups (John)

 - MD fixes via Yu Kuai:
      - raid1/raid10 fixes for writes_pending and barrier reference
        leaks on write and discard failures, plus REQ_NOWAIT handling
        fixes (Abd-Alrhman)
      - raid5 discard accounting and validation, and a batch of fixes
        for stripe batch races (Yu Kuai, Chen)
      - Protect raid1 head_position during read balancing (Chen)

 - block bio-integrity fixes: correct an error injection static key
   decrement, fix GFP flag confusion in bio_integrity_alloc_buf(), and
   handle REQ_OP_ZONE_APPEND in __bio_integrity_action() (Christoph)

 - Fixes for bio_iov_iter_bounce_write(): revert the iov_iter after a
   short copy, and respect the iov_iter nofault flag (Qu)

 - Invalidate the cached plug timestamp after a task switch, and clear
   PF_BLOCK_TS in copy_process() (Usama)

 - Fix the IORING_URING_CMD_REISSUE flags check in blkdev_uring_cmd()
   (Yitang)

 - Remove a redundant plug in __submit_bio() (Wen)

 - Don't warn when reclassifying a busy socket lock in nbd (Deepanshu)
