Subject: [Qemu-devel] [PATCH v2 14/23] hw: Convert from BlockDriverState to BlockBackend, mostly
Date: Sat, 13 Sep 2014 17:00:18 +0200 [thread overview]
Message-ID: <1410620427-20089-15-git-send-email-armbru@redhat.com> (raw)
In-Reply-To: <1410620427-20089-1-git-send-email-armbru@redhat.com>
Just four uses of BlockDriverState are left:
* The Xen paravirtual block device backend (xen_disk.c) opens images
itself when set up via xenbus, bypassing blockdev.c. I figure it
should go through qmp_blockdev_add() instead.
* Device model "usb-storage" prompts for keys. No other device model
does, and this one probably shouldn't do it, either.
* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
which has only the BlockDriverState.
* PC87312State has an unused BlockDriverState[] member.
The next two commits take care of the latter two.
