Let me make sure that I understand the current state:

1.	Fengguang pulls from my tree (presumably from rcu/next)	
	whenever I push something.  He tests my commits in isolation
	from other maintainers' commits.
	
2.	Stephen also pulls from my tree (rcu/next) whenever I push
	something.  However, Stephen tests the merge of all
	maintainers' commits.

So it sounds to me that Stephen is already doing the job that Steven
is suggesting should be done.

So, what am I missing here?

							Thanx, Paul
