Admittedly I know nothing about the kernel selftests although copying
the UAPI header, seems to defeat the purpose of this exercise.
Shouldn't one reuse the existing header ? It would even cause issues
as the interface gets updated (iirc Gustavo changed the ioctl numbers
and/or header name with latter series).
The problem is that one cannot use the system header without having
built and installed the kernel first, which is rather problematic for
eg. crosscompiling or virtualization. I discussed this with Gustavo and
we agreed that the best way forward would be to copy the interfaces, as
suggested by kernelnewbies' wiki[0]:
"""
The correct way to address this problem is to isolate the specific
interfaces that you need, e.g. a single header file that is patched in a
new kernel providing the ioctl numbers for a character device used by
your program. In your own program, add a copy of that source file, with
a notice that it should be kept in sync with new kernel versions.

Emilio
