This is public nobody cares. Likely I could make the reproducec with a
couple of prompts. 

What if you instead spent some time with your "short reproducer" and figure
out how to make equal reproducer with bash and keyctl? It's a good
habbit and helps to check the relevance because you have to think things
through.

This announcement is just total waste of time and energy anyhow.
