Subject: [Qemu-devel] [PATCH v2 13/20] raw: Switch to .bdrv_co_block_status()
Date: Fri, 14 Jul 2017 07:14:50 -0500 [thread overview]
Message-ID: <20170714121457.10322-14-eblake@redhat.com> (raw)
In-Reply-To: <20170714121457.10322-1-eblake@redhat.com>
We are gradually moving away from sector-based interfaces, towards
byte-based. Update the raw driver accordingly.
