CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	mbroz sourceware org	2012-03-26 20:33:40

Modified files:
	.              : WHATS_NEW 
	lib/locking    : locking.c 
	tools          : pvmove.c 

Log message:
	Keep exclusive activation in pvmove if LV is already active.
	
	Pvmove should never try to downgrade exclusive lock
	for LVs.
	
	This allows pvmove to work again for exclusive activated LVs.
