    Yes, that's the thing that I like with changes, too.
    Let's remove anything that can be removed. :)

    I'm just looking into buffer reference issue you mentioned.

    I already noticed that part of code that was dealing with buffer
    reference in shrink_mmap() disappeared some time ago. But I didn't
    have a slightest clue that fs/buffer.c survived such mass deletia, as
    one I just found in there. :)

    I'll implement simple buffer->page reference functionality, benchmark
    it and let you know what I've found.

    At this point, I think it will improve things, but let's wait and see.
