Subject: [PATCH] mm: memcg-v1: account vmpressure event allocations
Date: Mon, 13 Jul 2026 16:55:20 +0800 [thread overview]
Message-ID: <20260713085520.2953121-1-guopeng.zhang@linux.dev> (raw)
From: Guopeng Zhang <zhangguopeng@kylinos.cn>
Commit 72797d218b43 ("mm/memcg: v1: account event registrations and drop
world-writable cgroup.event_control") accounted cgroup v1 event
registration allocations with GFP_KERNEL_ACCOUNT, but missed struct
vmpressure_event.
Use GFP_KERNEL_ACCOUNT for this allocation as well.
Fixes: 72797d218b43 ("mm/memcg: v1: account event registrations and drop world-writable cgroup.event_control")
