Please drop this macro. <linux/compiler.h> takes care of it already.

Please drop the #ifdef

Please move the comment above the declaration (looks as if you're
breaking 80 columns).

Empty static inline functions are preferred.

Same here.

Move comment up.

Please move comment before function call and indent it properly.

Empty static inlines please.
