Yes, it is completely written by you. I verified it against the syzkaller
reproducer and reviewed the code logic.

If you prefer, I am happy to update the attribution, for example by replacing
Suggested-by with Co-developed-by, or by listing you as the author instead.  I
can also drop my patch if that is more appropriate.

Please let me know what you prefer.

Thanks.
