Subject: [PATCH v2 0/5] mm: memcg: merge page_counter trees

This patchset reorganizes page_counter structures which helps to make
memory cgroup and hugetlb cgroup structures smaller (10%-35% depending
on the kernel configuration) and more cache-effective. It also eliminates
useless tracking of protected memory usage when it's not needed.

v2:
  - two page_counter structures per hugetlb cgroup instead of one
  - rebased to the current mm branch
  - many minor fixes and improvements
v1:
  https://lore.kernel.org/lkml/20240503201835.2969707-1-roman.gushchin@linux.dev/T/#m77151ed83451a49132e29ef13d55e08b95ac867f


Roman Gushchin (5):
  mm: memcg: don't call propagate_protected_usage() needlessly
  mm: page_counters: put page_counter_calculate_protection() under
    CONFIG_MEMCG
  mm: memcg: merge multiple page_counters into a single structure
  mm: page_counters: initialize usage using ATOMIC_LONG_INIT() macro
  mm: memcg: convert enum res_type to mem_counter_type
