Alternatively, we could just remove the remaining instances in the kernel - cputime_t is the only borderline reasonable one there; xfs ones should be __bitwise and so should zd_addr_t thing (with cpu_to_le16() moved from uses of those suckers to macro definitions). Hell knows - I suspect that cputime_t also might've been turned into __bitwise u64, but I hadn't checked if we ever do plain arithmetics on those... -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
