#define TUNABLE_INT(path, var)                                  \
        static struct tunable_int __CONCAT(__tunable_int_, __LINE__) =3D { \

this is the code for TUNABLE_INT macro, the first param
to SYSINIT is an "uniquifier" which is "__Tunable_init_X"
where is is a number specifying line.

if I read it correctly there is no protection from collisions, am
I right?  is it a proper fix to concat __FILE__ there too?
