From 6bc3d1dc09d0ec158fb17ad7fcd8dcbcc37f89f9 Mon Sep 17 00:00:00 2001 From: Julian Elischer Date: Fri, 26 Oct 2007 22:18:20 +0000 Subject: [PATCH] If kthread_exit() is called on the last kthread in a kproc, then all the work in kproc_exit must be done. We don't actually have a user of this yet but why leave it to chance. --- sys/kern/kern_kthread.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/sys/kern/kern_kthread.c b/sys/kern/kern_kthread.c index cb231c8c6558..03d404bd801e 100644 --- a/sys/kern/kern_kthread.c +++ b/sys/kern/kern_kthread.c @@ -320,6 +320,12 @@ kthread_add(void (*func)(void *), void *arg, struct proc *p, void kthread_exit(void) { + /* + * We could rely on thread_exit to call exit1() but + * there is extra work that needs to be done + */ + if (curthread->td_proc->p_numthreads == 1) + kproc_exit(0); thread_exit(); }
