16 * 2000/07/13    acme		remove crap #if KERNEL_VERSION > blah
17 * 2000/01/21    acme            rename cyclomx_open to cyclomx_mod_inc_use_count
18 *                               and cyclomx_close to cyclomx_mod_dec_use_count
19 * 1999/05/19	acme		wait_queue_head_t wait_stats(support for 2.3.*)
20 * 1999/01/03	acme		judicious use of data types
