[lvm-devel] LVM2 tools/dmsetup.c ./WHATS_NEW



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac sourceware org	2011-08-04 12:40:25

Modified files:
	tools          : dmsetup.c 
	.              : WHATS_NEW 

Log message:
	Minor memory leak fix
	
	Defer the test of the function return value after the string memory is released.
	Otherwise in this error path the string would present memory leak.
	(Thought in this case we are already out of memory...)
