LVM2 lib/format_pool/import_export.c lib/metad ...

[wysochanski@sourceware.org <wysochanski@sourceware.org>]

CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski at sourceware.org	2010-04-13 17:26:03

Modified files:
	lib/format_pool: import_export.c 
	lib/metadata   : metadata.c 
	tools          : lvconvert.c vgmerge.c vgreduce.c 

Log message:
	Call add_pvl_to_vgs() and del_pvl_from_vgs() from more places.
	
	Now that we have library functions to add/delete a pv from the vg->pvs
	list, call them from everywhere.
