wait4(2)/waitid(2): separate copying rusage to userland 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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
