module: panic: Taint the kernel when selftest modules load
Taint the kernel with TAINT_TEST whenever a test module loads, by adding a new "TEST" module property, and setting it for all modules in the tools/testing directory. This property can also be set manually, for tests which live outside the tools/testing directory with: MODULE_INFO(test, "Y"); Reviewed-by: Luis Chamberlain <mcgrof@kernel.org> Reviewed-by: Aaron Tomlin <atomlin@redhat.com> Acked-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
