Hi Jon,

Thanks very much. I'll put these at the end of my patchset and attempt
to keep them building if I make changes to the core code (have to spend
a bit of time catching up with the review comments from last round).

I'll send out another patchset for review in a day or so after I catch
up, and then hopefully get it merged in -mm for 2.6.27.

Thanks,
Nick
