Subject: [PATCH 04/27] xor: move to lib/raid/
Date: Wed, 11 Mar 2026 08:03:36 +0100 [thread overview]
Message-ID: <20260311070416.972667-5-hch@lst.de> (raw)
In-Reply-To: <20260311070416.972667-1-hch@lst.de>
Move the RAID XOR code to lib/raid/ as it has nothing to do with the
crypto API.
Signed-off-by: Christoph Hellwig <hch@lst.de>
