SEQUENCE operation error recovery is very primative, we only reset the session.
Remove checking for any errors that are returned by the SEQUENCE operation, but
that resetting the session won't address.
NFS4ERR_RETRY_UNCACHED_REP, NFS4ERR_SEQUENCE_POS,NFS4ERR_TOO_MANY_OPS.
Add error checking for missing SEQUENCE errors that a session reset will
address.
NFS4ERR_BAD_HIGH_SLOT, NFS4ERR_DEADSESSION, NFS4ERR_SEQ_FALSE_RETRY.
A reset of the session is currently our only response to a SEQUENCE operation
error. Don't reset the session on errors where a new session won't help.
Don't reset the session on errors where a new session won't help.
