It's commented out because of locking problems. mi_switch() is often called with p_stat set to something else like SSLEEP or what not. If we block on the proc lock to do the psignal, then when we finally get the lock p_stat will be SRUN. We might be able to do the check at the very end of mi_switch() though. > Warner -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
