      SUNRPC: never enqueue a ->rq_cong request on ->sending · 29807318
      Neil Brown 提交于
      If the sending queue has a task without ->rq_cong set at the front,
      and then a number of tasks with ->rq_cong set such that they use
      the entire congestion window, then the queue deadlocks.  The first
      entry cannot be processed until later entries complete.
      
      This scenario has been seen with a client using UDP to access a server,
      and the network connection breaking for a period of time - it doesn't
      recover.
      
      It never really makes sense for an ->rq_cong request to be on the ->sending
      queue, but it can happen when a request is being retried, and finds
      the transport if locked (XPRT_LOCKED).  In this case we simple call
      __xprt_put_cong() and the deadlock goes away.
