Subject: [PATCH 09/17] drbd: remove bio_alloc_drbd
Date: Tue, 26 Jan 2021 15:52:39 +0100 [thread overview]
Message-ID: <20210126145247.1964410-10-hch@lst.de> (raw)
In-Reply-To: <20210126145247.1964410-1-hch@lst.de>
Given that drbd_md_io_bio_set is initialized during module initialization
and the module fails to load if the initialization fails there is no need
to fall back to plain bio_alloc.
