There isn't a single function in the entire kernel with an _ainline
suffix, while there are a ton of _inline suffixed functions.

On top of that, this function was already marked inline, and your
compiler just chose to not inline them for raisins. Just make the thing
__always_inline and forget, dont make thing extra ugly for no reason.
