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"

root@wan-koi.fnal.gov:/usr/obj/usr/src/sys/wenjikernel amd64
(2) "sysctl -a|grep lock"
$ sysctl -a|grep lock
