Hi Yoshihiro,

I do like your patch set, but I was thinking as this is becoming a new
ABI between the client and the server, I really want to spend a lot
more time looking at this before I pull it.

I'll be traveling again on Monday for 10 days (going to Kernel Summit
than the RT summit), and I'll try to review it more during my trip. But
even then, I really want to make sure the communication is robust. I
hate to have a "V3" and then need to support two older versions.

Thanks,

-- Steve
