However, the sock_update_classid function only updates classid's in sockets > if the tasks cgroup classid is not zero, and if it differs from the current > classid. The later check is to prevent cache line dirtying, but the former is > detrimental, as it prevents resetting a classid for a cgroup to 0. While this > is not a common action, it has administrative usefulness (if the admin wants to > disable classification of a certain group temporarily for instance). > > Easy fix, just remove the zero check.
