Subject: [PATCH v2 3/3] block: remove separate bdrv_file_open callback
Date: Thu, 1 Jun 2023 13:51:39 +0200 [thread overview]
Message-ID: <20230601115139.196369-4-pbonzini@redhat.com> (raw)
In-Reply-To: <20230601115139.196369-1-pbonzini@redhat.com>
bdrv_file_open and bdrv_open are completely equivalent, they are
never checked except to see which one to invoke. So merge them
into a single one.
