This is the change: r224016 | bz | 2011-07-14 14:18:14 +0000 (Thu, 14 Jul 2011) | 10 lines Remove semaphore map entry count "semmap" field and its tuning option that is highly recommended to be adjusted in too much documentation while doing nothing in FreeBSD since r2729 (rev 1.1). ipcs(1) needs to be recompiled as it is accessing _KERNEL private variables. Reviewed by: jhb (before comment change on linux code) Sponsored by: Sandvine Incorporated which suggests that the option has not done anything for a very long time. Cheers Tom
