Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A small collection of fixes that should go into this cycle. - a pull request from Christoph for NVMe, which ended up being manually applied to avoid pulling in newer bits in master. Mostly fibre channel fixes from James, but also a few fixes from Jon and Vijay - a pull request from Konrad, with just a single fix for xen-blkback from Gustavo. - a fuseblk bdi fix from Jan, fixing a regression in this series with the dynamic backing devices. - a blktrace fix from Shaohua, replacing sscanf() with kstrtoull(). - a request leak fix for drbd from Lars, fixing a regression in the last series with the kref changes. This will go to stable as well" * 'for-linus' of git://git.kernel.dk/linux-block: nvmet: release the sq ref on rdma read errors nvmet-fc: remove target cpu scheduling flag nvme-fc: stop queues on error detection nvme-fc: require target or discovery role for fc-nvme targets nvme-fc: correct port role bits nvme: unmap CMB and remove sysfs file in reset path blktrace: fix integer parse fuseblk: Fix warning in super_setup_bdi_name() block: xen-blkback: add null check to avoid null pointer dereference drbd: fix request leak introduced by locking/atomic, kref: Kill kref_sub()
