Subject: [PATCH 17/26] s390: move the XOR code to lib/raid/
Date: Tue, 24 Mar 2026 07:21:53 +0100 [thread overview]
Message-ID: <20260324062211.3216301-18-hch@lst.de> (raw)
In-Reply-To: <20260324062211.3216301-1-hch@lst.de>
Move the optimized XOR into lib/raid and include it it in xor.ko
instead of unconditionally building it into the main kernel image.
Signed-off-by: Christoph Hellwig <hch@lst.de>
Acked-by: Heiko Carstens <hca@linux.ibm.com>
