From d9b6cd94601e1d17273f93a326a135fbf487a918 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 31 Jul 2010 14:29:08 -0400 Subject: SUNRPC: Ensure that rpc_exit() always wakes up a sleeping task Make rpc_exit() non-inline, and ensure that it always wakes up a task that has been queued. Kill off the now unused rpc_wake_up_task().
