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

[wysochanski at sourceware.org]

CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski at sourceware.org	2010-04-13 17:25:45

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

Log message:
	Add del_pvl_from_vgs() and move prototypes into metadata-exported.h
	
	Add a delete function to manage the vg->pvs list.
	
	NOTE: It may be possible to do further cleanup to these add/del functions
	by passing a 'pv' as input instead of 'pv_list'.  The pv_list is used for
	functions which do allocations (lvcreate) while other places in the code
	just manage a list of 'pv' (e.g. import functions, vgextend, etc).
