Author: marcel Date: Sun Feb 8 23:39:30 2009 New Revision: 188352 URL: http://svn.freebsd.org/changeset/base/188352 Log: Allow gpe_offset to be set by the scheme. When gpe_offset is zero, or invalid, initialize it to the start of the partition. Adjust the mediasize when the offset lies somewhere inside the partition.
