LVM2/lib/format_text format-text.c

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

CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	snitzer at sourceware.org	2009-07-30 17:41:02

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

Log message:
	Remove legacy support for preserving pe_start if a PV already has data
	areas.
	
	This preserved pe_start would quickly be readjusted to follow the first
	mda anyway.  An example use-case that hit this code path is: running
	pvcreate on an already existing PV _without_ a preceeding pvremove.
