[PATCH v2 0/2] mm: memcg: fix tracking of pending stats updates values

From: Yosry Ahmed
Date: Fri Sep 22 2023 - 14:00:10 EST


While working on adjacent code [1], I realized that the values passed
into memcg_rstat_updated() to keep track of the magnitude of pending
updates is consistent. It is mostly in pages, but sometimes it can be in
bytes or KBs. Fix that.

Patch 1 reworks memcg_page_state_unit() so that we can reuse it in patch
2 to check and normalize the units of state updates.

v1 -> v2:
- Rebased on top of mm-unstable.
