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

Pull block fixes from Jens Axboe:
 "A set of fixes for the current series in the realm of block.

  Like the previous pull request, the meat of it are fixes for the nvme
  fabrics/target code.  Outside of that, just one fix from Gabriel for
  not doing a queue suspend if we didn't get the admin queue setup in
  the first place"

* 'for-linus' of git://git.kernel.dk/linux-block:
  nvme-rdma: add back dependency on CONFIG_BLOCK
  nvme-rdma: fix null pointer dereference on req->mr
  nvme-rdma: use ib_client API to detect device removal
  nvme-rdma: add DELETING queue flag
  nvme/quirk: Add a delay before checking device ready for memblaze device
  nvme: Don't suspend admin queue that wasn't created
  nvme-rdma: destroy nvme queue rdma resources on connect failure
  nvme_rdma: keep a ref on the ctrl during delete/flush
  iw_cxgb4: block module unload until all ep resources are released
  iw_cxgb4: call dev_put() on l2t allocation failure
