| H A D | umh.c | diff d300b610812f3c10d146db4c18f98eba38834c70 Sun Mar 11 05:34:26 CDT 2018 Dominik Brodowski <linux@dominikbrodowski.net> kernel: use kernel_wait4() instead of sys_wait4()
All call sites of sys_wait4() set *rusage to NULL. Therefore, there is
no need for the copy_to_user() handling of *rusage, and we can use
kernel_wait4() directly.
This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see
