Subject: [dm-devel] [PATCH 2/5] drbd: use PAGE_SECTORS_SHIFT and PAGE_SECTORS
Date: Fri, 21 Apr 2023 12:58:04 -0700	[thread overview]
Message-ID: <20230421195807.2804512-3-mcgrof@kernel.org> (raw)
In-Reply-To: <20230421195807.2804512-1-mcgrof@kernel.org>

Replace common constants with generic versions.
This produces no functional changes.
