Subject: Make sure all changes to md/array_state are notified.
X-Git-Tag: v2.6.27-rc1~957^2~44
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0fd62b861eac7d2dea9b7e939953b20f37186ea1;p=pandora-kernel.git

Make sure all changes to md/array_state are notified.

Changes in md/array_state could be of interest to a monitoring
program.  So make sure all changes trigger a notification.

Exceptions:
   changing active_idle to active is not reported because it
      is frequent and not interesting.
   changing active to active_idle is only reported on arrays
      with externally managed metadata, as it is not interesting
      otherwise.
