You can use atomic_long_inc_return() if you want the new value.
So the "atomic_fetch_op()" is a "fetch old value and do the op".
The "atomic_op_return()" is "do the op and return the new value".
We do have both, although on x86, the "fetch_op" is the one that most
closely then maps to "xadd".
But if you find the current code easier, that's fine.
