summary of current pending changes in aio-next.git

[Benjamin LaHaise]

The first 10 of Kent's AIO optimization series have been pulled into my 
tree as summarised below.  I had to rework some of the patches to correctly 
apply after Gu Zheng's polishing of the AIO ringbuffer migration support, 
so any extra eyes on those changes would be helpful.  I also fixed a couple 
of bugs in the table lookup patch, as well as eliminating a BUG_ON() Kent 
added in order to be a bit more defensive.

These changes should show up in linux-next, so please give them a beating.  
I plan to post a few more changes against this tree in the next couple of 
weeks.
