Subject: [PATCH v8 34/43] block: Drop backing_bs()
Date: Tue,  1 Sep 2020 16:34:15 +0200	[thread overview]
Message-ID: <20200901143424.884735-35-mreitz@redhat.com> (raw)
In-Reply-To: <20200901143424.884735-1-mreitz@redhat.com>

We want to make it explicit where bs->backing is used, and we have done
so.  The old role of backing_bs() is now effectively taken by
bdrv_cow_bs().
