Based on that. I had dropped the inode operation as it's not really a generic operation but a callback for either the buffered I/O code or direct I/O and should be treated as such. I've also split the single multiplexer function into individual ones, but the underlying data structure and fundamental operations are the same.

Your version defintively was up on your kernel.org XFS tree, that's what I started from.
I'll have a long plane right tonight, let's see if I can get the direct I/O version updated.
