    wait4(2)/waitid(2): separate copying rusage to userland · ce72a16f
    Al Viro authored
    New helpers: kernel_waitid() and kernel_wait4().  sys_waitid(),
    sys_wait4() and their compat variants switched to those.  Copying
    struct rusage to userland is left to syscall itself.  For
    compat_sys_wait4() that eliminates the use of set_fs() completely.
    For compat_sys_waitid() it's still needed (for siginfo handling);
    that will change shortly.
