Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe: "A small collection of fixes that has been gathered over the last few weeks. This contains: - A one-liner fix for NVMe, fixing a missing list_head init that could makes us oops on hitting recovery at load time. - Two small blk-mq fixes: - Fixup a bad goto jump on error handling. - Fix for oopsing if running out of reserved tags. - A memory leak fix for NBD. - Two small writeback fixes from Tejun, fixing a missing init to INITIAL_JIFFIES, and a possible underflow introduced recently. - A core merge fixup in sg gap detection, where rq->biotail was indexed with the count of rq->bio" * 'for-linus' of git://git.kernel.dk/linux-block: writeback: fix possible underflow in write bandwidth calculation NVMe: Initialize device list head before starting Fix bug in blk_rq_merge_ok blkmq: Fix NULL pointer deref when all reserved tags in blk-mq: fix use of incorrect goto label in blk_mq_init_queue error path nbd: fix possible memory leak writeback: add missing INITIAL_JIFFIES init in global_update_bandwidth()
