Subject: [Qemu-devel] [PATCH 02/17] blkreplay: Convert to byte-based I/O
Date: Tue, 21 Jun 2016 11:21:19 +0200	[thread overview]
Message-ID: <1466500894-9710-3-git-send-email-kwolf@redhat.com> (raw)
In-Reply-To: <1466500894-9710-1-git-send-email-kwolf@redhat.com>

The blkreplay driver only forwards the requests it gets, so converting
it to byte granularity is trivial.
