Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"Another week, another round of fixes.
These have been brewing for a bit and in various iterations, but I
feel pretty comfortable about the quality of them. They fix real
issues. The pull request is mostly blk-mq related, and the only one
not fixing a real bug, is the tag iterator abstraction from Christoph.
But it's pretty trivial, and we'll need it for another fix soon.
Apart from the blk-mq fixes, there's an NVMe affinity fix from Keith,
and a single fix for xen-blkback from Roger fixing failure to free
requests on disconnect"
* 'for-linus' of git://git.kernel.dk/linux-block:
blk-mq: factor out a helper to iterate all tags for a request_queue
blk-mq: fix racy updates of rq->errors
blk-mq: fix deadlock when reading cpu_list
blk-mq: avoid inserting requests before establishing new mapping
blk-mq: fix q->mq_usage_counter access race
blk-mq: Fix use after of free q->mq_map
blk-mq: fix sysfs registration/unregistration race
blk-mq: avoid setting hctx->tags->cpumask before allocation
NVMe: Set affinity after allocating request queues
xen/blkback: free requests on disconnection
