Olga Kornievskaia 9b332c7229 SUNRPC: add a missing rpc_stat for TCP TLS ... [ Upstream commit 8e088a20db ] Commit 1548036ef1 ("nfs: make the rpc_stat per net namespace") added functionality to specify rpc_stats function but missed adding it to the TCP TLS functionality. As the result, mounting with xprtsec=tls lead to the following kernel oops.
