46 * Theoretically, directories can be more than 2Gb in length,
47 * however, in practice this seems unlikely. So, we define
48 * the type doff_t as a long to keep down the cost of doing
49 * lookup on a 32-bit machine. If you are porting to a 64-bit
50 * architecture, you should make doff_t the same as off_t.
