[GIT PULL] block fixes for 7.4-rc2

[GIT PULL] block fixes for 7.4-rc2

[Jens Axboe]

Hi Linus,

Block fixes for this week. Mostly NVMe via Keith, with a handful of
core and driver fixes. This pull request contains:

- NVMe fixes via Keith:
  - nvme-tcp use-after-free in nvme_tcp_free_ctrl() on a failed
    connect, and the nvme-rdma counterpart of the NULL queue->ctrl on
    reconnect
  - nvmet-rdma iWARP disconnect and device removal fixes
  - nvmet-tcp: ask for the TLS record type on every receive, and
    bound the connections accepted per work run so a connect flood
    can't hold up port removal; nvmet-auth keep the old keys if the
    new ones fail to decode; nvme-loop delete the controller if a
    reset fails
  - nvmet-auth reject incomplete DHCHAP messages, and a keep-alive
    timeout overflow
  - nvmet locking and bounds fixes for tbkas reconnects and the
    traddr/trsvcid configfs writes, don't leak stale memory in the
    ANA log page, and cache the passthru reference across
    queue_response
  - Wait for SRCU readers before splicing the namespace list, with a
    new list_splice_init_srcu() helper, and drop an extra grace
    period in nvmet_ns_disable()
  - Unregister when pr_register() is given a zero new key, and don't
    drop the cdev reference twice on cdev_device_add() failure
  - Quirks for the ADATA XPG GAMMIX S70 BLADE and KIOXIA XG10d
  - Various smaller fixes and cleanups

- blk-mq: end the request if getting a keyslot fails, which left the
  in-flight count and zone write plug stuck, reset the queue state on
  scheduler teardown so requests don't stall in software queues, and
  fix an out-of-bounds read in blk_mq_free_rqs() after a failed
  nr_hw_queues update

- Only serialize elevator switches of the same queue

- dma-buf bio fixes: don't use the bvec fast path for them, and only
  fail the ones that need block layer PI

- Reject GPT entries with starting_lba > ending_lba

- Return the soft block size for compat BLKBSZGET, report the correct
  discard alignment in sysfs, and account the flush sequence latency
  only once in iocost

- virtio_blk fixes: synchronous quiesce in freeze, freeze the virtqueue
  layout at probe time, clamp max_segments to the ring size, and fix
  zone append sector reporting in batched completion

- null_blk zone fixes and a cache state reset

- zloop fixes

- ublk DEL_DEV_ASYNC permission check, and 32-bit selftest build

Please pull!
