It seems this patch got lost and I don't see it in recent 'resend'
series. K.Y., Dexuan, can you please take a look?
Hi Vitaly, Jason,
The patch can't fix all the corner cases (it would need non-trivial
efforts for that)
as we discussed, but I think it would be better for us to have it as
it can indeed fix
an obvious issue and doesn't introduce new issues.
I think I can document the known discussed corner cases in the patch
as TODOs
and resend the patch.
Please let me know if you have different opinions. :-)
Thanks,
-- Dexuan
Yes, I think it's ok.
We can do other fixes on top.
Thanks
