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

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.

Michal,

Do you mind taking a looking at the entire series?

Thank you.

Yu Zhao (13):
  mm: use add_page_to_lru_list()
  mm: use page_off_lru()
  mm: move __ClearPageLRU() into page_off_lru()
  mm: shuffle lru list addition and deletion functions
  mm: don't pass enum lru_list to lru list addition functions
  mm: don't pass enum lru_list to trace_mm_lru_insertion()
  mm: don't pass enum lru_list to del_page_from_lru_list()
  mm: rename page_off_lru() to __clear_page_lru_flags()
  mm: inline page_lru_base_type()
  mm: VM_BUG_ON lru page flags
  mm: inline __update_lru_size()
  mm: make lruvec_lru_size() static
  mm: enlarge the int parameter of update_lru_size()
