CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski@sourceware.org	2009-07-09 10:04:52

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

Log message:
	Rename vg_change_pesize to vg_set_extent_size and use vg_t.
	
	In liblvm, we will reserve the word 'change' to mean an API that
	both sets one or more values, and commits to disk.  This will be
	consistent with the LVM commandline.  The existing vg_change_pesize()
	function does not commit to disk, but just changes the extent_size
	and ensures all internal structures are updated.  This logic should
	be contained in a function that sets the value.
