46 * TP_BSIZE is the size of file blocks on the dump tapes.
47 * Note that TP_BSIZE must be a multiple of DEV_BSIZE.
49 * NTREC is the number of TP_BSIZE blocks that are written
50 * in each tape record. HIGHDENSITYTREC is the number of
51 * TP_BSIZE blocks that are written in each tape record on
52 * 6250 BPI or higher density tapes.
54 * TP_NINDIR is the number of indirect pointers in a TS_INODE
55 * or TS_ADDR record. Note that it must be a power of two.
