V4: Use variable for /sys/kernel/debug. Be consistent with "" around variables. Fix path in commit message to /sys/kernel/debug/kprobes/enabled. 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.
