I'm wrong on this one, it's actually opening a socket with O_NONBLOCK
that fails with EINVAL, and then we pass -1 to the above. I saw
something on boot on O_NONBLOCK being the wrong value (I think from
systemd), so maybe another case of userspace and the kernel not agreeing
on what values flags/errno has?

In any case, with the silly syzbot mmap stuff fixed up, I'm not seeing
anything odd. A few tests will time out as they simply run too slowly
emulated for me, but apart from that, seems fine. This is running with
Helge's patch, though not sure if that is required running emulated.
