Subject: [PATCH 14/24] block: Inline bdrv_set_backing_noperm()
Date: Fri, 27 Oct 2023 17:53:23 +0200 [thread overview]
Message-ID: <20231027155333.420094-15-kwolf@redhat.com> (raw)
In-Reply-To: <20231027155333.420094-1-kwolf@redhat.com>
It's only a single line and has a single caller. Inlining makes things
a bit easier to follow.
