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.
Regards, -- Zlatko
