[GIT PULL] Block fixes for 7.2-rc3

[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

A set of block fixes for 7.2-rc3. This contains:

- Limit blk_hctx_poll() to one jiffy. Prevents buggy drivers from
  spinning for too long, hence triggering a stalled RCU read secion
  warning.

- Avoid a potential deadlock on zone revalidation failure, which could
  otherwise trigger a lockdep circular locking splat during a SCSI disk
  rescan.

- Remove a redundant GD_NEED_PART_SCAN set in add_disk_final().

- Make writes to queue/wbt_lat_usec honor the WBT enable state.

- ublk fix to snapshot the batch commands before preparing IO, so that
  userspace can't change an already processed tag and trip the
  WARN_ON_ONCE() in the rollback path.

- xen-blkfront fix for a double completion of split requests on resume.

- drbd fix to reject data replies with an out-of-range payload size.

Please pull!
