Hi Linus,
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.
Please pull!
