Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A selection of fixes/changes that should make it into this series. This contains: - NVMe, two merges, containing: - pci-e, rdma, and fc fixes - Device quirks - Fix for a badblocks leak in null_blk - bcache fix from Rui Hua for a race condition regression where -EINTR was returned to upper layers that didn't expect it. - Regression fix for blktrace for a bug introduced in this series. - blktrace cleanup for cgroup id. - bdi registration error handling. - Small series with cleanups for blk-wbt. - Various little fixes for typos and the like. Nothing earth shattering, most important are the NVMe and bcache fixes" * 'for-linus' of git://git.kernel.dk/linux-block: (34 commits) nvme-pci: fix NULL pointer dereference in nvme_free_host_mem() nvme-rdma: fix memory leak during queue allocation blktrace: fix trace mutex deadlock nvme-rdma: Use mr pool nvme-rdma: Check remotely invalidated rkey matches our expected rkey nvme-rdma: wait for local invalidation before completing a request nvme-rdma: don't complete requests before a send work request has completed nvme-rdma: don't suppress send completions bcache: check return value of register_shrinker bcache: recover data from backing when data is clean bcache: Fix building error on MIPS bcache: add a comment in journal bucket reading nvme-fc: don't use bit masks for set/test_bit() numbers blk-wbt: fix comments typo blk-wbt: move wbt_clear_stat to common place in wbt_done blk-sysfs: remove NULL pointer checking in queue_wb_lat_store blk-wbt: remove duplicated setting in wbt_init nvme-pci: add quirk for delay before CHK RDY for WDC SN200 block: remove useless assignment in bio_split null_blk: fix dev->badblocks leak ...
