This was part of an agreement (obviously) with BSDI to improve FreeBSD's SMP processing. For this purpose I received three source trees, labeled 4.1-RELEASE, 4.1 and 5.0-smp-devel. I still have them, and as far as I can see they're complete. Clearly they weren't maintained under git, since it didn't exist yet. The headers suggest RCS or (probably) CVS. For example: * BSDI exec_elf.c,v 1.7 1998/08/24 19:03:08 torek Exp * BSDI kern_fork.c,v 2.10 1999/04/20 22:40:19 cp Exp None of this was "open sourced"; we were allowed to use it for this specific purpose.

You might also be interested in my report of the meeting which set this off, at http://www.lemis.com/grog/diary-jun2000.php#15 In passing, it was an interesting experience. Both BSD/OS and FreeBSD derived from (most recently) 4.4BSD Lite, but they had diverged to a point where it was really painful to merge the code. Greg -- Sent from my desktop computer.
