LOCK_PROFILING does not work on FreeBSD 8.0-CURRENT

[Wenji Wu]

I, Could anybody help me out? Thanks in advance. 

LOCK_PROFILING does not work on FreeBSD 8.0-CURRENT. I loaded FreeBSD 8.0-Current on my system, and try to run LOCK PROFILING. I have added the “options    LOCK_PROFILING” to the configure file and rebuild the kernel. Then I reboot the system, and run “sysctl –a|grep lock” to check if the lock debugging has been enabled. But NO lock debugging related parameters show up. LOCK_PROFILING does not work on FreeBSD 8.0-CURRENT!

I have repeated the same operations on FreeBSD 7.1, “sysctl –a|grep lock” shows “LOCK PROFILING” works. So what happens to FreeBSD 8.0-CURRENT?

Thanks,
