From 659f90f863a628c007c49aff97b30cb5908a0480 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michal=20Koutn=C3=BD?= Date: Mon, 9 Sep 2024 18:32:21 +0200 Subject: [PATCH] cgroup/cpuset: Expose cpuset filesystem with cpuset v1 only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The cpuset filesystem is a legacy interface to cpuset controller with (pre-)v1 features. It makes little sense to co-mount it on systems without cpuset v1, so do not build it when cpuset v1 is not built neither.
