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.
