[PATCH] md: fix calculation of ->degraded for multipath and raid10
Two less-used md personalities have bugs in the calculation of ->degraded (the extent to which the array is degraded). Signed-off-by: Neil Brown <neilb@suse.de> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
