Subject: [RFC PATCH v2 3/3] misc_cgroup: delete failed logs to avoid log flooding

From: Chunguang Xu <>

Since the upper-level logic will constantly retry when it fails, in
high-stress scenarios, a large number of failure logs may affect
performance. Therefore, we can replace it with the failcnt counter.
