It's even more or less required by the coding style. Chapter 5
(typedefs) 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.

So this is probably an improvement in any case.

Thanks,
Frans
