[GIT PULL] Block fixes for 7.3-rc6

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A set of block fixes for this week. Mostly NVMe via a pull from Keith,
but also a few core block and driver fixes. This pull request contains:

- NVMe fixes via Keith:
	- Fix an out-of-bounds write in nvmet_auth_challenge(), where
	  sizeof() on a void pointer undercounted the challenge header and
	  let a short AUTH_RECEIVE buffer pass the check
	- nvme-multipath fixes for an ANA log bounds check underflow, the
	  command effects log lifetime for multipath heads, and only
	  setting BLK_FEAT_ZONED after the zone info is known.
	- nvmet fixes for ns->enabled teardown ordering, rejecting I/O
	  after the percpu ns reference is killed, device path preservation
	  on allocation failure, and too-short SGL segments in pci-epf
	- nvme-tcp: revert the per-socket dynamic lockdep keys, and delay
	  the socket reclassification
	- A DMA pool alignment quirk for the Micron 4100AT
	- Controller state/reset race fixes, and -Wformat-security
	  workarounds

- blk-mq: set RQF_USE_SCHED when the operation is known, and allow
  cached requests to be used for flush operations

- Reject polled dio with user integrity metadata

- Save the IRQ state in blkg_tryget_closest()

- Set the zone write granularity in virtio_blk

- ublk selftest fixes

Please pull!
