+ 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:
