I am thinking about FreeBSD, it will not compile there.

You need <linux/const.h> only for string glue macro, so maybe:
# define _AC(X,Y) X##Y
and drop include <linux/const.h> ?
Btw if #ifndef, then maybe something like:
#ifndef _AC
# define _AC(X,Y) X##Y
#else
# error "_AC macro already defined"
#endif
to prevent some silent macro redefinitions and hard to spot bugs?

Ok, you are right, there are new files so thats why it is needed
