Glen Overby knows the dir2 format the best after
Doug Doucette.

Glen, Doug, any suggestions on what to look for
when hitting the last assert below:

         * Loop over the data/unused entries.
        while (p < endp) {
                dup = (xfs_dir2_data_unused_t *)p;
                 * If it's unused, look for the space in the bestfree table.
                 * If we find it, account for that, else make sure it
                 * doesn't need to be there.
                if (INT_GET(dup->freetag, ARCH_UNKNOWN) == 
                        ASSERT(lastfree == 0);
                               (char *)dup - (char *)d);
