Hi Deepa,

This is a very nice series, sorry for taking way too long before
I had a good look at it.

The first two patches in particular are great. The third patch
looks like it has a small bug that I commented on, but given
how much more thought you have put into this than I did, it's
just as possible that I misunderstood it.

I've applied you series locally now, but have not pushed it out
yet for linux-next because of that one issue. I'll send a pull
request to Thomas for my other patches for now, and a
follow-up with these once we have clarified it.

        Arnd
