 * TP_BSIZE is the size of file blocks on the dump tapes.
 * Note that TP_BSIZE must be a multiple of DEV_BSIZE.
 *
 * NTREC is the number of TP_BSIZE blocks that are written
 * in each tape record.
 *
 * TP_NINDIR is the number of indirect pointers in a TS_INODE
 * or TS_ADDR record. Note that it must be a power of two.
