Subject: [Qemu-devel] [PATCH 18/19] commit: Simplify reopen of base
Date: Wed, 20 Dec 2017 11:34:11 +0100	[thread overview]
Message-ID: <20171220103412.13048-19-kwolf@redhat.com> (raw)
In-Reply-To: <20171220103412.13048-1-kwolf@redhat.com>

Since commit bde70715, base is the only node that is reopened in
commit_start(). This means that the code, which still involves an
explicit BlockReopenQueue, can now be simplified by using bdrv_reopen().
