Subject: [PATCH v1 0/4] Page counters optimizations
Date: Fri, 3 May 2024 13:18:31 -0700 [thread overview]
Message-ID: <20240503201835.2969707-1-roman.gushchin@linux.dev> (raw)
From: Roman Gushchin <roman.gushchin@getcruise.com>
This patchset reorganizes page_counter structures which helps to make
memory cgroup and hugetlb cgroup structures smaller (20%-35%) and
more cache-effective. It also eliminates useless tracking of protected
memory usage when it's not needed.

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