Subject: [PATCH 15/20] block: remove the nr_sectors variable in generic_make_request_checks
Date: Wed,  1 Jul 2020 10:59:42 +0200
Message-ID: <20200701085947.3354405-16-hch@lst.de> (raw)
In-Reply-To: <20200701085947.3354405-1-hch@lst.de>

The variable is only used once, so just open code the bio_sector()
there.
