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
