commit 24ca9a847791fd53d9b217330b15f3c285827a18
Author: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx>

    SUNRPC: Ensure we return EAGAIN in xs_nospace if congestion is cleared
    
    By returning '0' instead of 'EAGAIN' when the tests in xs_nospace() fail
    to find evidence of socket congestion, we are making the RPC engine believe
    that the message was incorrectly sent and so it disconnects the socket
    instead of just retrying.
    
    The bug appears to have been introduced by commit
    5e3771ce2d6a69e10fcc870cdf226d121d868491 (SUNRPC: Ensure that xs_nospace
    return values are propagated).
