[lvm-devel] LVM2 ./WHATS_NEW lib/locking/locking.c lib/loc ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	mbroz sourceware org	2010-01-22 09:45:30

Modified files:
	.              : WHATS_NEW 
	lib/locking    : locking.c no_locking.c 
	liblvm         : lvm_base.c 
	tools          : lvmcmdline.c 

Log message:
	Move error message to locking constructor and print
	more descriptive message if locking fails instead of
	"Locking type -1 initialisation failed."
	
	Use read-only locking instead of misleading ignorelocking option
	in message.
