[PATCH v2 0/4] vmscan per-cgroup reclaim fixes

Changes since v1:
- Added acks.
- Dropped "mm/vmscan: replace mm_vmscan_lru_shrink_inactive with shrink_page_list tracepoint"
patch. It's better to avoid changing the tracepoint as some people may be used to it.
Removing 'nr_scanned' and 'file' arguments is also not very good. Yes, these numbers could
be obtained from mm_vmscan_lru_isolate tracepoint, but it's easier when it's all in one place.

- Compare with nr_writeback,dirty, etc only isolated file pages as it always was.
- Minor changelog tweaks.

Andrey Ryabinin (4):
mm/vmscan: Update stale comments
mm/vmscan: remove redundant current_may_throttle() check
mm/vmscan: Don't change pgdat state on base of a single LRU list
state.
mm/vmscan: Don't mess with pgdat->flags in memcg reclaim.
