Paolo Abeni 3391f526fc mptcp: fix lockdep false positive in mptcp_pm_nl_create_listen_socket() ... commit cee4034a3d upstream. Christoph reports a lockdep splat in the mptcp_subflow_create_socket() error path, when such function is invoked by mptcp_pm_nl_create_listen_socket(). Such code path acquires two separates, nested socket lock, with the internal lock operation lacking the "nested" annotation. Adding that in sock_release() for mptcp's sake only could be confusing. Instead just add a new lockclass to the in-kernel msk socket, re-initializing the lockdep infra after the socket creation.
