From 96ef13b283934fbf60b732e6c4ce23e8babd0042 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 22 Feb 2008 15:46:41 -0500 Subject: SUNRPC: Add a new helper rpc_wake_up_queued_task() In all cases where we currently use rpc_wake_up_task(), we almost always know on which waitqueue the rpc_task is actually sleeping. This will allows us to simplify the queue locking in a future patch.
