51 * TP_BSIZE is the size of file blocks on the dump tapes.
52 * Note that TP_BSIZE must be a multiple of DEV_BSIZE.
54 * NTREC is the number of TP_BSIZE blocks that are written
55 * in each tape record. HIGHDENSITYTREC is the number of
56 * TP_BSIZE blocks that are written in each tape record on
57 * 6250 BPI or higher density tapes.
59 * TP_NINDIR is the number of indirect pointers in a TS_INODE
60 * or TS_ADDR record. Note that it must be a power of two.
