md/raid5: Fix a bug about judging if the operation is syncing or replacing
When create a raid5 using assume-clean and echo check or repair to
sync_action.Then component disks did not operated IO but the raid
check/resync faster than normal.
Because the judgement in function analyse_stripe():
if (do_recovery ||
sh->sector >= conf->mddev->recovery_cp)
s->syncing = 1;
else
s->replacing = 1;
When check or repair,the recovery_cp == MaxSectore,so syncing equal zero
not one.
This bug was introduced by commit 9a3e1101b827
md/raid5: detect and handle replacements during recovery.
so this patch is suitable for 3.3-stable.
