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"
