    NFSv4: Handle timeouts correctly when probing for lease validity · bc7a05ca
    Trond Myklebust authored
    When we send a RENEW or SEQUENCE operation in order to probe if the
    lease is still valid, we want it to be able to time out since the
    lease we are probing is likely to time out too. Currently, because
    we use soft mount semantics for these RPC calls, the return value
    is EIO, which causes the state manager to exit with an "unhandled
    error" message.
    This patch changes the call semantics, so that the RPC layer returns
    ETIMEDOUT instead of EIO. We then have the state manager default to
    a simple retry instead of exiting.
