Subject: [PATCH v3 1/4] drbd: use PAGE_SECTORS_SHIFT and PAGE_SECTORS
Date: Fri, 15 Sep 2023 15:43:40 -0700	[thread overview]
Message-ID: <20230915224343.2740317-2-mcgrof@kernel.org> (raw)
In-Reply-To: <20230915224343.2740317-1-mcgrof@kernel.org>

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