Thus, code that does this: error = suser_td(td); if (error) return (error); is going to become this: struct proc *p = td->td_proc; PROC_LOCK(p); error = suser(p); if (error) { PROC_UNLOCK(p); return; } .... /* do stuff */ PROC_UNLOCK(p); I originally asked that the suser_td() changes not be made so that the locking code doesn't have to go back all of them out again thus increasing the overall diff size. -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
