/* DESCRIPTION:
   fast_lock_data.free_list_head is lock_list_head. fast_lock_data.list is the
   first two words of lock_list_block.  Other lock_list_block's are threaded
   to make a list.  block_data is large enough to contain 
   fast_lock_wakeup_block (largest fast lock block type).
*/

/* HISTORY:
Written by John Bongiovanni, 06/15/82.
Modified:
10/12/84 by Stanford S. Cox:  Added version constants.
11/14/84 by Stanford S. Cox:  Removed lock_list_head.version as fast_lock_data
   has a version.

Historical Background

This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group Bull including Bull HN Information Systems Inc. 
as a contribution to computer science knowledge.  
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell Bull Inc., Groupe Bull
and Bull HN Information Systems Inc. to the development of this operating system. 
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for 
managing computer hardware properly and for executing programs. Many subsequent operating systems 
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., 
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
