Subject: [PATCH v2 0/9] memcg: cleanup per-cpu stock
Date: Thu,  3 Apr 2025 18:39:04 -0700	[thread overview]
Message-ID: <20250404013913.1663035-1-shakeel.butt@linux.dev> (raw)

This is a cleanup series which is trying to simplify the memcg per-cpu
stock code, particularly it tries to remove unnecessary dependencies on
local_lock of per-cpu memcg stock. The eight patch from Vlastimil
optimizes the charge path by combining the charging and accounting.

This series is based on mm-everything-2025-04-03-06-03. The main changes
from v1 is collecting acks, adding warning in patch 1 and rebased on the
latest local lock changes from Alexei.


Shakeel Butt (8):
  memcg: remove root memcg check from refill_stock
  memcg: decouple drain_obj_stock from local stock
  memcg: introduce memcg_uncharge
  memcg: manually inline __refill_stock
  memcg: no refilling stock from obj_cgroup_release
  memcg: do obj_cgroup_put inside drain_obj_stock
  memcg: use __mod_memcg_state in drain_obj_stock
  memcg: manually inline replace_stock_objcg

Vlastimil Babka (1):
  memcg: combine slab obj stock charging and accounting
