Subject: [PATCH 4/5] dm bufio: simplify by using PAGE_SECTORS_SHIFT
Date: Fri, 21 Apr 2023 12:58:06 -0700	[thread overview]
Message-ID: <20230421195807.2804512-5-mcgrof@kernel.org> (raw)
In-Reply-To: <20230421195807.2804512-1-mcgrof@kernel.org>

The PAGE_SHIFT - SECTOR_SHIFT constant be replaced with PAGE_SECTORS_SHIFT
defined in linux/blt_types.h, which is included by linux/blkdev.h.

This produces no functional changes.
