But why do this?

We don't care about lustre, especially as it is not merged into the main

Seriously, work on fixing up the known issues in lustre before adding
additional features, I've only been saying this for a few _years_ now...

This whole patch series is broken, always test-build your code, there's
nothing we could do with these patches even if we wanted to :(
