The diff between the two version doesn't show too much other possible
interesting commits, the most interesting being some minor block
updates.
I guess we'll have to a manual bisect, I've pushed out a
scsi-mq.3-bisect-1 branch that is rebased to just before the merge of
the block tree, and a scsi-mq.3-bisect-2 branch that is just after
the merge of the block tree to get started.
