Subject: [PATCH 1/2] block/bdev: use helper for max block size check
Date: Tue, 17 Dec 2024 18:02:11 -0800 [thread overview]
Message-ID: <20241218020212.3657139-2-mcgrof@kernel.org> (raw)
In-Reply-To: <20241218020212.3657139-1-mcgrof@kernel.org>
We already have a helper for checking the limits on the block size
both low and high, just use that.
No functional changes.
