v4: Drop patch 1. [Cornelia]
Add the last trivial patch.
v3: Rebase to master.
Squash 4 into 3. [Paolo]
Add comment and commit message. [Stefan]
Add Stefan's r-b in patch 1 and 2.
v2: Only convert virtio-{blk,scsi}. [Paolo]
The benifit of this is we don't use event_notifier_set_handler even in
non-dataplane now, which in turn makes virtio-blk and virtio-scsi follow block
layer aio context semantics. Specifically, I/O requests must come from
blk_get_aio_context(blk) events, rather than iohandler_get_aio_context(), so
that bdrv_drained_begin/end will work as expected.
Patch 4 reverts the hack (ab27c3b5e7) we added for 2.6. Lately, commit
b880481579 added another pair of bdrv_drained_begin/end so the crash cannot
happen even without ab27c3b5e7, but in order to avoid leaking requests, patch
two is still a must.

completion"
