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



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	prajnoha sourceware org	2011-03-02 10:23:29

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

Log message:
	Use a copy if moving an mda from pv fid to vg fid.
	
	We'll destroy the pv fid (with all mdas in it) after merging all pv mdas to
	a vg in _text_pv_setup fn, hence we need to use a copy here!
