From: Mikulas Patocka This patch suppresses this warning: drivers/md/dm-raid.c: In function 'raid_ctr': drivers/md/dm-raid.c:427:54: warning: 'rebuilds_per_group' may be used uninitialized in this function [-Wmaybe-uninitialized] drivers/md/dm-raid.c:383:11: note: 'rebuilds_per_group' was declared here The warning doesn't represent a real bug (rebuilds_per_group is always initialized in the first iteration of a loop), but gcc can't deduce it.
