[PATCH 00/13] mm: clean up some lru related pieces

From: Yu Zhao

Hi Andrew,

I see you have taken this:
mm: use add_page_to_lru_list()/page_lru()/page_off_lru()
Do you mind dropping it?

Michal asked to do a bit of additional work. So I thought I probably
should create a series to do more cleanups I've been meaning to.

This series contains the change in the patch above and goes a few
more steps farther. It's intended to improve readability and should
not have any performance impacts. There are minor behavior changes in
terms of debugging and error reporting, which I have all highlighted
in the individual patches. All patches were properly tested on 5.8
running Chrome OS, with various debug options turned on.


Do you mind taking a looking at the entire series?

Thank you.
