Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "A set of fixes that should go into this series. This contains:

   - Fix from Bart for blk-mq requeue queue running, preventing a
     continued loop of run/restart.

   - Fix for a bio/blk-integrity issue, in two parts. One from
     Christoph, fixing where verification happens, and one from Milan,
     for a NULL profile.

   - NVMe pull request, most of the changes being for nvme-fc, but also
     a few trivial core/pci fixes"

* 'for-linus' of git://git.kernel.dk/linux-block:
  nvme: fix directive command numd calculation
  nvme: fix nvme reset command timeout handling
  nvme-pci: fix CMB sysfs file removal in reset path
  lpfc: support nvmet_fc defer_rcv callback
  nvmet_fc: add defer_req callback for deferment of cmd buffer return
  nvme: strip trailing 0-bytes in wwid_show
  block: Make blk_mq_delay_kick_requeue_list() rerun the queue at a quiet time
  bio-integrity: only verify integrity on the lowest stacked driver
  bio-integrity: Fix regression if profile verify_fn is NULL
