Is it allowed to use _Static_assert() in UAPI header files? There are already
some static_assert() checks under include/linux to verify the size of certain
data structures. gcc supports _Static_assert() since version 4.6. That is older
than the minimum required gcc version to build the kernel.
Thanks,
Bart.
