Although I don't know Lai personally, from my experience working with
him past several months on workqueue, I strongly doubt he has dark
urterior intenions.  The biggest problem probably is that his
communication in English isn't very fluent yet and thus doesn't carry
the underlying intentions or tones very well and he tends to bombard
patches in quick succession without much explanation inbetween (during
3.8 cycle, I was receiving several workqueue patchsets days apart
trying to solve the same problem with completely different approaches
way before the discussion on the previous postings reach any kind of
consensus).  A lot of that also probably comes from communication
problems.

Anyways, I really don't think he's trying to take claim of your work.
At least for now, you kinda need to speculate what he's trying to do
and then confirm that back to him, but once you get used to that part,
he's pretty nice to work with and I'm sure his communication will
improve in time (I think it has gotten a lot better than only some
months ago).

Thanks!
