Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "A set of fixes that wasn't included in the first merge window pull request. This pull request contains: - A set of NVMe fixes from Keith, and one from Nic for the integrity side of it. - Fix from Ming, clearing ->mq_ops if we don't successfully setup a queue for multiqueue. - A set of stability fixes for bcache from Jiri, and also marking bcache as orphaned as it's no longer actively maintained (in mainline, at least)" * 'for-linus' of git://git.kernel.dk/linux-block: blk-mq: clear q->mq_ops if init fail MAINTAINERS: mark bcache as orphan bcache: bch_gc_thread() is not freezable bcache: bch_allocator_thread() is not freezable bcache: bch_writeback_thread() is not freezable nvme/host: Add missing blk_integrity tag_size + flags assignments NVMe: Add device ID's with stripe quirk NVMe: Short-cut removal on surprise hot-unplug NVMe: Allow user initiated rescan NVMe: Reduce driver log spamming NVMe: Unbind driver on failure NVMe: Delete only created queues NVMe: Allocate queues only for online cpus
