Subject: [PATCH 0/3] block/io: serialising request clean up and locking fix
Date: Wed, 18 Dec 2019 14:17:03 +0100 [thread overview]
Message-ID: <1576675026-25046-1-git-send-email-pbonzini@redhat.com> (raw)
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.
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
