That only checks for one of the conditions, trying to map something
offset/overlapping the end of the buffer, but small enough needs to be
tested separately.
you mean test for smaller length with a non-zero offset? I don't think I
get what you wanted to say here maybe.
Also I think a testcase for invalid buffer2fd flags would be good, just
for completeness - we seem to be missing that one.
you mean test for different flags than the ones supported by
DRM_IOCTL_PRIME_HANDLE_TO_FD?
