From: Joe Lawrence <joe.lawrence@redhat.com> Since livepatching depends upon ftrace handlers to implement "patched" code functionality, verify that the ftrace_enabled sysctl value interacts with livepatch registration as expected. At the same time, ensure that ftrace_enabled is set and part of the test environment configuration that is saved and restored when running the selftests.
