[lvm-devel] LVM2 lib/metadata/metadata-exported.h lib/meta ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2009-10-05 20:03:08

Modified files:
	lib/metadata   : metadata-exported.h metadata.c 
	liblvm         : lvm_vg.c 

Log message:
	Allow calling fill_default_pvcreate_params from tools.
	
	We need defaults for pvcreate_params at a higher level - this will
	allow us to use a common function from the tools to take defaults,
	then fill in any non-defaults from the commandline.
	
	Future patches will refactor vgcreate/vgextend to call this function
	if one or more pvcreate parameters are given on the commandline.
