From 7a1218a277c45cba1fb8d7089407a1769c645c43 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 20 Mar 2006 18:11:10 -0500 Subject: SUNRPC: Ensure rpc_call_async() always calls tk_ops->rpc_release() Currently this will not happen if we exit before rpc_new_task() was called. Also fix up rpc_run_task() to do the same (for consistency).
