Subject: [PATCH] Docs/admin-guide/cgroup-v2: fix memory.stat doc details
Date: Sat, 20 Jun 2026 12:27:51 +0000 [thread overview]
Message-ID: <20260620122751.388770-1-doehyunbaek@gmail.com> (raw)
Fix minor cgroup v2 memory.stat documentation issues. Correct the
vmalloc per-node marker now that vmalloc uses the native NR_VMALLOC node
stat, and document zswap_incomp as a byte-valued memory amount instead
of as a page counter.
Fixes: c466412c73c3 ("mm: memcontrol: switch to native NR_VMALLOC vmstat counter")
Fixes: 5ad41a38c364 ("mm: zswap: add per-memcg stat for incompressible pages")
