Failed to build it on latest archlinux

[STRRL]

I setup a vm with latest archlinux. When try to install chaos driver with yay, it tells me:

In Linux 5.16, someone moves the public elevator.h to an internal private directory, and this repo cannot compile. Maybe I should hurry up to submit the related patch to the kernel mainline (but I'm not sure whether it will be accepted).

[STRRL]

I got that. I would use an earlier kernel to try it.
