Subject: [PATCH 1/9] tracing: Convert module refcnt events to DEFINE_EVENT
Date: Thu, 26 Nov 2009 15:03:23 +0800	[thread overview]
Message-ID: <4B0E283B.3010508@cn.fujitsu.com> (raw)
In-Reply-To: <4B0E2807.4060102@cn.fujitsu.com>

Use TRACE_EVENT_TEMPLATE to remove duplicate code:

   text    data     bss     dec     hex filename
  29854    1980     128   31962    7cda kernel/module.o.old
  28750    1980     128   30858    788a kernel/module.o

Two events are converted:

  module_refcnt: module_get, module_put
