CONFIG_TEST_KMOD: kmod stress tester

General informations

The Linux kernel configuration item CONFIG_TEST_KMOD:

Help text

Test the kernel's module loading mechanism: kmod. kmod implements support to load modules using the Linux kernel's usermode helper. This test provides a series of tests against kmod.

Although technically you can either build test_kmod as a module or into the kernel we disallow building it into the kernel since it stress tests request_module() and this will very likely cause some issues by taking over precious threads available from other module load requests, ultimately this could be fatal.

To run tests run:

tools/testing/selftests/kmod/ --help

If unsure, say N.
