[lvm-devel] LVM2 daemons/clvmd/clvmd-command.c ./WHATS_NEW



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac sourceware org	2010-12-17 12:37:50

Modified files:
	daemons/clvmd  : clvmd-command.c 
	.              : WHATS_NEW 

Log message:
	Fix NULL pointer check for *buf
	
	As ternary operator has lower priority then add operation, this check
	was not doing what seemed to be expected.
	
	So enclose the test in braces and check for NULL in *buf.
