Help text

Test kernel livepatching features for correctness. The tests will load test modules that will be livepatched in various scenarios.

To run all the livepatching tests:

make -C tools/testing/selftests TARGETS=livepatch run_tests

Alternatively, individual tests may be invoked:

tools/testing/selftests/livepatch/test-callbacks.sh tools/testing/selftests/livepatch/test-livepatch.sh tools/testing/selftests/livepatch/test-shadow-vars.sh

If unsure, say N.
