This patch corrects the following: - Enhances the AdvFS verify utility to detect incorrect "holes" in the frags file. - Enhancement for the /sbin/advfs/verify utility allows it to detect loops in the list of free frags kept in the frags file. - Avoids corruption of a filesystem when verify runs with '-r' & '-f' flags on an active domain. Verify returns usage message when '-r' flag is used with either '-f' or '-d'.
