From: Namhyung Kim Date: Mon, 13 Jun 2011 05:48:22 +0000 (+0900) Subject: md/raid5: fix raid5_set_bi_hw_segments X-Git-Tag: v3.0-rc4~98^2~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b2dc8b665932a8e681a7ab3237f60475e75e161;p=pandora-kernel.git md/raid5: fix raid5_set_bi_hw_segments The @bio->bi_phys_segments consists of active stripes count in the lower 16 bits and processed stripes count in the upper 16 bits. So logical-OR operator should be bitwise one. This bug has been present since 2.6.27 and the fix is suitable for any -stable kernel since then. Fortunately the bad code is only used on error paths and is relatively unlikely to be hit. Cc: stable@kernel.org Signed-off-by: Namhyung Kim Signed-off-by: NeilBrown --- Reading git-diff-tree failed
