Hi Linus,

Bigger than usual for an end-of-merge-window pull request, main reason
being that the MD side I had missed a pull on, and both NVMe and block
got a good pile of LLM driven fixes where some of them may as well just
go in now rather than wait a full cycle. This pull request contains:

- NVMe fixes via Keith:
  - nvme-tcp fallout from the parallel queue allocation: initialize
    pf_cache_lock and the header digest before requests are set up,
    and don't dereference a NULL queue->ctrl on reconnect
  - nvme-fabrics queue mapping fixes: reset io_queues on reconnect,
    limit each queue type to the online CPUs, and clear a poll map
    with no poll queues
  - nvme-tcp io_work priority inversion with send_mutex held (Seiji),
    error recovery on read_sock failure and skipping TLS control
    records while waiting for the ICResp (Martin B), TLS handshake
    timeout validation, and an address attribute race
  - nvme-rdma NULL metadata_sgl dereference with T10-PI
  - nvme-pci early boot hang with the quirks parameter
  - nvme-multipath ANA log bounds underflow, and an nvme-fc discovery
    reference leak
  - nvmet hardening: rdma inline SGL out-of-bounds write and short
    connect requests, fc use-after-free in LS create connection and
    teardown on admin queue failure, pci-epf transport error reporting
    and SGL length checks, zns NUMD wrap, fc stale read data, auth
    state and status fixes, ports list and qid_max locking, rdma
    double puts and irq-safe locking, and a double free on metadata
    SGL allocation failure
  - nvmet fixes from Josef: big discard length truncation, NULL derefs
    for PCI endpoint targets and debugfs host_traddr, stop listening
    when a tcp port is removed, and don't BUG() in nvme-loop when a
    scan runs beside a reset

- MD fixes via Yu Kuai:
  - raid5 validation: reject too few disks, invalid reshape disks, a
    per-device size below one chunk, and an inconsistent reshape state
    from the superblock instead of BUG(), plus journal payload size
    checks
  - raid5 error path and lifetime fixes: extra_page leak and NULL
    derefs in free_conf/setup_conf, draining released_stripes before
    destroying the cache, RCU for the big_stripe_tree lookup, and
    per-array io_unit slab names
  - md core: reject v0.90 arrays with too many devices, validate
    bblog_size, take reconfig_mutex when enabling PPL, fix the
    mddev->private NULL deref when stopping an array under IO, and
    don't hand out the array before mddev->kobj is added
  - raid10 missing barrier wakeup, raid0 device count validation, a
    bogus mddev_unlock() in lbs_store(), and shared helpers

- blk-mq fixes from Josef: don't trust the bio cookie in blk_mq_poll(),
  keep tag sharing fair after a queue update, don't bring back flags of
  a completed request from the timeout handler, honor a restarted
  timer, initialize the dma state for P2P, quiesce a queue joining a
  quiesced tag set, set up and exit hctxs under tag_list_lock, and free
  the tag bitmaps in the SRCU callback

- blk-cgroup and friends from Josef: keep the old blkg while
  reassociating a bio, free struct ioc after a grace period, don't
  truncate v1 iops limits, fix root io.stat on 32-bit, don't free a
  blkg with its punt work queued, flush iolatency enable_work after
  going offline, pass dead group I/O counts on and make reset_stats
  reset them, and don't enter reclaim under rq_qos_mutex

- Other core fixes from Josef: a disk use-after-free in sync_bdevs(),
  not losing the status of a failed flush request, 64-bit sector math
  for mac partitions, and applying the segment size to the integrity
  buffer

- blk-iocost: abort a weight transfer on invalid donation weights, and
  publish hweights as one atomic value

- Fix a NULL deref and use-after-free in __blk_crypto_evict_key(),
  reachable via dm-inlinecrypt

- Fix recursive i_rwsem locking in blkdev_write_iter(), from two fixes
  for the same race landing in the window

- Advance the iterator after copy-in for SG_DXFER_TO_FROM_DEV, fixing
  an infinite loop in blk_rq_map_user_iov()

- Check the open mode for LOOP_SET_STATUS in the compat ioctl

- rnbd-srv use-after-free and kobject fixes

- drbd timer and req_lock fixes

- zloop cleanups and error path fixes

- cdrom header and kernel-doc cleanups

Please pull!
