What kind of portability should exported userspace headers from Linux kernel
need?
Reviews to my previous changes NACKed <stdint.h> usage and
Documentation/CodingStyle chapter 5 says:
(e) Types safe for use in userspace.
In certain structures which are visible to userspace, we cannot
require C99 types and cannot use the 'u32' form above. Thus, we
use __u32 and similar types in all structures which are shared
with userspace.
