Subject: [PATCH 1/9] brd: remove the end of device check in brd_do_bvec
Date: Tue,  1 Dec 2020 17:54:16 +0100	[thread overview]
Message-ID: <20201201165424.2030647-2-hch@lst.de> (raw)
In-Reply-To: <20201201165424.2030647-1-hch@lst.de>

The block layer already checks for this conditions in bio_check_eod
before calling the driver.
