Patch 1 checks the return value of waitpid(), which GCC warns about. Patch 2 fixes a check which never matches, so that a child reporting a failure no longer lets the tests pass. Tested in QEMU (virt, rv64 with and without V) on a v7.3-rc1 defconfig kernel, running vstate_prctl as init: - vstate_prctl passes 13/13 with and without the series. - With the child's vstate_ctrl check forced to fail, it still passes 13/13 without patch 2, and fails the 6 affected tests with it. - The warning is gone with GCC 14.2 and 16.2.
