I'm not very familiar with mdadm, but how does you patch help here? Once a 
month /etc/cron.d/mdadm is doing a resync.

# cat /proc/mdstat 
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] 
[raid10] 
md1 : active raid1 sda3[0] sdb3[1]
      133821376 blocks [2/2] [UU]
      [=====>...............]  check = 29.6% (39666624/133821376) 
finish=24.1min speed=64932K/sec

unused devices: <none>

check_linux_raid is reporting "OK md1 status=[UU]." with and without of your 
patch.
Under which conditions matches your regex? Do you have an example and when 
will this happen?

Thanks and with kind regards, Jan.
