Subject: [PATCH 0/9] memcg: cleanup per-cpu stock

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 next-20250314 plus two following patches:

  memcg: decouple drain_obj_stock from local stock
  memcg: introduce memcg_uncharge
  memcg: manually inline __refill_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
