This patchset adds a test for livepatching a kprobed function. Thanks to Petr and Marcos for the reviews! V3: Save and restore kprobe state also when test fails, by integrating it into setup_config() and cleanup(). Rename SYSFS variables in a more logical way. Sort test modules in alphabetical order. Rename module description. V2: Save and restore kprobe state.
