PyNFS testclient.py SESSIONRESET tests The INJECT_ERROR testclient.py test where NFS4ERR_BADSESSION was returned every 50th SEQUENCE operation and the session destroyed durring a Connectathon basic test run. This passed all but the bigfile test where the check_lease op->renew_lease nfs4_proc_sequence state manager session reset call could not get a slot due to the async error handler restart read/write RPC's getting slots prior to any rpc tasks waiting on queues. This will be fixed in a subsequent patch set. v4 mount: Connectathon tests passed. no CONFIG_NFS_V4_1 v4 mount: Connectathon tests passed. -->Andy ~ -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
