Subject: [PATCH v3 03/21] block: Drop bdrv_is_first_non_filter()
Date: Thu, 30 Jan 2020 22:44:13 +0100 [thread overview]
Message-ID: <20200130214431.333510-4-mreitz@redhat.com> (raw)
In-Reply-To: <20200130214431.333510-1-mreitz@redhat.com>
It is unused now. (And it was ugly because it needed to explore all BDS
chains from the top.)
