[Qemu-block] [PATCH for-2.9 0/5] Sheepdog cleanups

[Paolo Bonzini]

Cleaning up the code and removing duplication makes it simpler to
later adapt it for the multiqueue work.

Tested against sheepdog 1.0.  I also tested taking snapshots and reverting
to older snapshots, but the latter only worked with "dog vdi rollback".
Neither loadvm nor qemu-img worked for me.

Paolo Bonzini (5):
  sheepdog: remove unused cancellation support
  sheepdog: reorganize coroutine flow
  sheepdog: do not use BlockAIOCB
  sheepdog: simplify inflight_aio_head management
  sheepdog: reorganize check for overlapping requests
