Subject: [RFC 1/4] iomap: use BLK_MAX_BLOCK_SIZE for the iomap zero page
Date: Thu, 20 Mar 2025 04:13:25 -0700 [thread overview]
Message-ID: <20250320111328.2841690-2-mcgrof@kernel.org> (raw)
In-Reply-To: <20250320111328.2841690-1-mcgrof@kernel.org>
There is no point in modifying two locations now that we have
a sensible BLK_MAX_BLOCK_SIZE defined which is only lifted once
we have tested and validated things.
