Subject: [Qemu-devel] [PATCH 3/4] block: Simplify use of BDRV_BLOCK_RAW.
Date: Thu, 18 May 2017 21:32:32 -0500	[thread overview]
Message-ID: <20170519023233.24461-4-eblake@redhat.com> (raw)
In-Reply-To: <20170519023233.24461-1-eblake@redhat.com>

The lone caller that cares about a return of BDRV_BLOCK_RAW
completely replaces the return value, so there is no point in
passing BDRV_BLOCK_DATA.
