Hi Shaohua,
thanks for explaining a bit more your thinking about this code.
I've been testing and reviewing and found a few bugs and done some
cleaning up (e.g. share code). It seems to be working OK and I'm
starting to feel confident about it.
Could you please review all of these patches and confirm that the
changes I have made are consistent with your understanding of how it
should work? Maybe if you could test (there are all in my for-next
branch) and make sure the performance improvements are still there,
that would be great.
Thanks,
NeilBrown
