p The function .Fn kproc_start is used to start "internal" daemons and intended to be called from .Fn SYSINIT 9 . The function .Fn kthread_create is used to create a kernel process/thread. It shares its address space with proc0; kernel only. The function .Fn kthread_exit is used to terminate kernel processes/threads. To suspend and resume a kernel thread/process, the functions .Fn suspend_kproc and .Fn resume_kproc are used. Participation in this scheme is voluntary. .Sh SEE ALSO .Xr SYSINIT 9
