[PATCH 004 of 9] md: Tidy up device-change notification when an md array is stopped

From: NeilBrown
Date: Tue Nov 07 2006 - 17:12:58 EST



An md array can be stopped leaving all the setting still in place,
or it can torn down and destroyed.
set_capacity and other change notifications only happen in the latter
case, but should happen in both.
