SUNRPC: Run rpc timeout functions as callbacks instead of in softirqs
An audit of the current RPC timeout functions shows that they don't really ever need to run in the softirq context. As long as the softirq is able to signal that the wakeup is due to a timeout (which it can do by setting task->tk_status to -ETIMEDOUT) then the callback functions can just run as standard task->tk_callback functions (in the rpciod/process context). The only possible border-line case would be xprt_timer() for the case of UDP, when the callback is used to reduce the size of the transport congestion window. In testing, however, the effect of moving that update to a callback would appear to be minor. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
