AFAIK __always_inline is the only reliable way to force inlining where it matters for correctness (for example, when playing tricks with __builtin_return_address like we do in the slab).
Anything else is just a hint to the compiler that might be ignored if the optimizer thinks it knows better. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
