From 46d65096ce8d278abf4528e254878c14ddd0b459 Mon Sep 17 00:00:00 2001 From: Doehyun Baek Date: Sat, 20 Jun 2026 12:27:51 +0000 Subject: [PATCH] Docs/admin-guide/cgroup-v2: fix memory.stat doc details MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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") Signed-off-by: Doehyun Baek Reviewed-by: Nhat Pham Acked-by: Michal Koutný Signed-off-by: Tejun Heo --- Documentation/admin-guide/cgroup-v2.rst | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Documentation/admin-guide/cgroup-v2.rst b/Documentation/admin-guide/cgroup-v2.rst index 993446ab66d0..ce6741f78f4f 100644 --- a/Documentation/admin-guide/cgroup-v2.rst +++ b/Documentation/admin-guide/cgroup-v2.rst @@ -1570,7 +1570,7 @@ The following nested keys are defined. sock (npn) Amount of memory used in network transmission buffers - vmalloc (npn) + vmalloc Amount of memory used for vmap backed memory. shmem @@ -1735,7 +1735,7 @@ The following nested keys are defined.
