    Add regexp for Linux SW RAID devices in /proc/partitions (#678379)
    
    Add regular expression to detect the device entry only (e.g., md127)
    and not the partitions (e.g., md127p1).
    
    Linux software RAID devices are listed in /proc/partitions as follows:
    
    # cat /proc/partitions
    major minor  #blocks  name
       9   127     523968 md127
     259     0     131072 md127p1
     259     1     262144 md127p2
    
    Part of Bug #678379 - Could not stat device /dev/md/0 - No such file
                          or directory
