For some reason some of your patches are not coming through with correct 
diffstats (notice the lack of a path relative to the kernel base?).  
Don't worry too much about it as it's not grounds to reject the patch 
(at least in my mind) but it's worth looking into on your end for the 
next time you submit patches.

In cases like this where you need patches applied atomically to ensure 
correct operation you can always combine the two patches into one 
(assuming they are still small enough to be posted, which shouldn't be 
a problem here).  Small patches are nice and easy to review, but that 
doesn't mean you have to break everything up if it is awkward.

I've looked over patches #7, #8, and #9 and they look okay to me, but 
I'm not tagging them 'Reviewed-by' because they go beyond areas of the 
kernel that I feel comfortable reviewing at this point.  Rest assured 
there are other on the To/CC line that can help you out (I see James 
Morris already Ack'd your entire patch set).

Thanks for all your work on this, it's a nice improvement.
