Subject: cgroup_rm_file: don't delete the uncreated files
From: Gao feng <[email protected]>
commit f33fddc2b9573d8359f1007d4bbe5cd587a0c093 upstream.
in cgroup_add_file,when creating files for cgroup,
some of creation may be skipped. So we need to avoid
deleting these uncreated files in cgroup_rm_file,
otherwise the warning msg will be triggered.
"cgroup_addrm_files: failed to remove memory_pressure_enabled, err=-2"
