From 909a3f0e9d8b0d8001cf6e99808f88eca8e44328 Mon Sep 17 00:00:00 2001 From: Cheng Lingfei Date: Mon, 24 Aug 2026 20:45:46 +0800 Subject: docs: cgroup-v2: fix misc.events key format description MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In misc cgroup, misc.events does not output a simple "max" key. Instead, each registered misc resource outputs a separate key suffixed with ".max" (i.e., ".max"). Update the documentation to clarify that the entry key is ".max".
