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
21* 1998/12/27	acme		cleanup: PACKED not needed
