      [PATCH] Provide a 'safe-mode' for soft raid. · 063e9f83
      Neil Brown authored
      When a raid1 or raid5 array is in 'safe-mode', then the array
      is marked clean whenever there are no outstanding write requests,
      and is marked dirty again before allowing any write request to
      proceed.
      
      This means than an unclean shutdown while no write activity is happening
      will NOT cause a resync to be required.  However it does mean extra
      updates to the superblock.
      
      Currently safe-mode is turned on by sending SIGKILL to the raid thread
      as would happen at a normal shutdown.  This should mean that the
      reboot notifier is no longer needed.
      
      After looking more at performance issues I may make safemode be on
      all the time.  I will almost certainly make it on when RAID5 is degraded
      as an unclean shutdown of a degraded RAID5 means data loss.

      Neil Brown authored
      From Art Haas <ahaas@airmail.net>:
      
      This converts md.c to use C99 initializers to improve readability and
      remove warnings if '-W' is used.
