Can't resist, smp_mb__before_atomic() should equally work, but this doesn't really matter, please forget.
We really should have "test_bit_acquire()" and "set_bit_release()".
Well, we do have the test_bit_acquire().
We just don't have the set_bit side, because we only have the bit clearing version (and it's called "clear_bit_unlock()" for historical reasons).
Annoying.
