From 5d00837b90340af9106dcd93af75fd664c8eb87f Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 22 Feb 2008 16:34:17 -0500 Subject: 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.
