[lvm-devel] LVM2/tools vgmerge.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2009-09-02 21:28:27

Modified files:
	tools          : vgmerge.c 

Log message:
	Refactor vgmerge - combine _vgmerge_to and _vgmerge_from into _vgmerge_vg_read.
	
	These functions are identical so should be no functional change.
