From a0131c39270de634c33950a799d8870da2191974 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michal=20Koutn=C3=BD?= Date: Fri, 14 Nov 2025 19:21:27 +0100 Subject: [PATCH] docs: cgroup: No special handling of unpopulated memcgs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The current kernel doesn't handle unpopulated cgroups any special regarding reclaim protection. Furthermore, this wasn't a case even when this was introduced in bf8d5d52ffe89 ("memcg: introduce memory.min") Drop the incorrect documentation. (Implementation taking into account the inner-node constraint may be added later.)
