Yes, as I mentioned in mail to Christoph, I did it just to separate kevent as much as possible (so I introduced ->get_block() based approach). It can be safely moved into mpage code and used from more clear callback like ->readpage(). Since this AIO code was decided to be postponed for a while, I'm not updating it (just make sure that it compiles with new changes), since overall design of AIO changes (if any) is not 100% completed.
