Dueling inode scalability patches

I hope Linus merges Nick's patchset. Dave just wants to get something merged, no matter what. Al seems to want too much changes at once. Al also created (or is going to) a branch where he puts in the common cleanups/pacthes from both Dave's and Nick's and wants them to base their patches against the new branch, so they're easier to compare. This seems like a very good idea and should move things forwards.
