Olga Kornievskaia 7f6023610b NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION ... [ Upstream commit c907e72f58 ] When the client received NFS4ERR_BADSESSION, it schedules recovery and start the state manager thread which in turn freezes the session table and does not allow for any new requests to use the no-longer valid session. However, it is possible that before the state manager thread runs, a new operation would use the released slot that received BADSESSION and was therefore not updated its sequence number. Such re-use of the slot can lead the application errors.
