From ddea95c1c2e32c6454c89aa83d78b26a83564cd4 Mon Sep 17 00:00:00 2001 Message-Id: From: Pavel Hrdina Date: Mon, 1 Jul 2019 17:07:11 +0200 Subject: [PATCH] Revert "vircgroup: cleanup controllers not managed by systemd on error" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit 1602aa28f820ada66f707cef3e536e8572fbda1e. There is no need to call virCgroupRemove() nor virCgroupFree() if virCgroupEnableMissingControllers() fails because it will not modify 'group' at all. The cleanup of directories is done in virCgroupMakeGroup().
