Subject: [PATCH v5 0/3] selftests: livepatch: test livepatching a kprobed function

Thanks for all the reviews.

V5:
Replace /sys/kernel/livepatch also in other/already existing tests.
Improve commit message of 3rd patch.

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.
