shared tag queue barrier comment Should add some comments for the tag barriers (they won't be so important if we can switch over to the explicit _lock bitops, but for now we should make it clear). Jens' original patch said a barrier after the test_and_clear_bit was also required. I can't see why (and it would prevent the use of the _lock bitop).
