From: "Tobin C. Harding" <tobin@kernel.org> mainline inclusion from mainline-v5.1-rc4 commit 6989808ee7636188cc091224bc76ab8e1696088a category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4BUC2 CVE: NA ----------------------------------------------------- Currently the test_printf module does not have an exit function, this prevents the module from being unloaded. If we cannot unload the module we cannot run the tests a second time. Add an empty exit function. Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Tobin C.
