    pnfs: layout roc code · f7e8917a

    A layout can request return-on-close.  How this interacts with the
    forgetful model of never sending LAYOUTRETURNS is a bit ambiguous.
    We forget any layouts marked roc, and wait for them to be completely
    forgotten before continuing with the close.  In addition, to compensate
    for races with any inflight LAYOUTGETs, and the fact that we do not get
    any layout stateid back from the server, we set the barrier to the worst
    case scenario of current_seqid + number of outstanding LAYOUTGETS.
