Re: LOCK_PROFILING does not work on FreeBSD 8.0-CURRENT

Here is my procedures:

(1) run "cvsup supfile" to synchronize the latest kernel

(2) edit my kernel configuration file, and add "options 	LOCK_PROFILING" to my kernel configuration file

(3) run "make buildkernel KERNCONF=wenjikernel"

(4) run "make installkernel kernconf=WENJIKERNEL"

(5) run "reboot" to reboot my system.

Here is the system printout after the reboot.

(1) "$ uname -a"
FreeBSD wan-koi.fnal.gov 8.0-CURRENT FreeBSD 8.0-CURRENT #8: Sun Mar 29 20:11:07 UTC 2009     
root_at_wan-koi.fnal.gov:/usr/obj/usr/src/sys/wenjikernel  amd64

(2) "sysctl -a|grep lock"
$ sysctl -a|grep lock
