Hi Mickaël and Günther,

I received the following report about a failing landlock selftest from
the 0day bot.

I was unable to run the landlock selftests myself, on my machines they are
failing at runtime with all kinds of colorful errors. Are the requirements
explained somewhere?

This error number means "EAGAIN 11 Resource temporarily unavailable",
so it could be a temporary error.

Can you reproduce this issue? Is it really dependent on my patch as
blamed above? If so, does the selftest rely on the previous, incorrect order?
