Peter Lieven noticed that reqs->overlap_offset and reqs->overlap_bytes
are written outside bs->reqs_lock. Patch 3 fixes it, while patches 1
and 2 are preparatory cleanups.
v1->v2: fix comment in patch 2, commit message in patch 3 [Kevin]
Paolo Bonzini (3):
block: eliminate BDRV_REQ_NO_SERIALISING
block/io: wait for serialising requests when a request becomes
serialising
block/io: take bs->reqs_lock in bdrv_mark_request_serialising
