From: Weng Meiling <wengmeiling.w...@huawei.com> Unloading the cgroup filesystem with cgclear -l config, if there is an umount subsystem in the mount section. The error message is "cgclear failed with Success". This is broken. So fix it, replace the error message with "cgclear failed with Cgroup invalid operation",
This patch checks whether the subsystem is mounted before umount the cgroup filesystem. For multi subsystems mounted on one place in the config, just only all subsystems are not mounted, report the error.
