Hello my dear io_uring friends

Today I tried to run my tests on a different, more powerful hardware
(70+ Hyperthreads) and it crashed on creating the ring.

I don't recall anything fancy in my code for creating the ring -
except maybe that I size the cq ring differently than the sq ring.

The backtrace attached leads me to believe that we just accessed a
null struct somewhere
