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,
