[linux-lvm] Snapshot resizing pe_allocated correction

[Dale J. Stephenson]

Another slight fix.  When a snapshot is resized, the volume groups' 
pe_allocated field is not updated.  The following patch should fix this 
problem:

+++ linux/drivers/md/lvm.c	Mon Apr 29 12:41:29 2002

+	vg_ptr->pe_allocated += new_lv->lv_allocated_le;

 	return 0;
 }
