CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	agk at sourceware.org	2011-07-05 18:36:37

Modified files:
	lib/activate   : activate.c 

Log message:
	Always perform preload logic before suspending - not only in the case when we
	have precommitted metadata.  (Necessary to avoid loading tables
	while suspend in lvchange --refresh.)
