There is no need to include <linux/kernel.h> here.

Prefer the less invasive <linux/types.h> and <linux/compiler_types.h>
which are needed in this .h file itself.

Not sure we really need the comment here, we don't comment on the
other includes either.  Also why the added empty line?

Ok for the comment, I'll remove it.
In header files, sometimes, when not obvious, we find such comments. 
Sometimes we don't.

For the empty line, it was mostly a matter of taste. My goal was to 
explicitly show that one was <uapi/linux, and the other one only <linux/

I'll remove it as well.

My main point, was only to remove kernel.h.
