Subject: [RFC PATCH] selftests: fanotify: Add basic create/modify/delete event

Thanks for the feedback!

I agree LTP has very comprehensive fanotify/inotify tests.

However, the motivation for adding basic tests to kernel selftests is:
    - Quick and lightweight regression checking during kernel
    development/boot (no external LTP install needed)
    - Non-root basic cases (many LTP tests require root or complex setup)

Similar to how selftests/mm or selftests/net have basic syscall wrappers
even though LTP covers them deeply.

Do you think a different approach (LTP improvement instead)
would be better?

Thanks,
Jinseok
