[lvm-devel] LVM2/lib/format_text format-text.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2010-06-29 13:29:53

Modified files:
	lib/format_text: format-text.c 

Log message:
	Attempt to fix intermittent failure with non-debug configured vgcfgbackup.
	
	There's an intermittent failure with vgcfgbackup that seems to have been
	introduced with the metadataignore / vgmetadatacopies patchset.
	Intermittent failures are often the result of uninitialized data,
	so this patch calls zalloc in a few places it might matter.
