    The patch from Li Zefan you've already queued is better

    Subject: [PATCH 03/13] tracing: Move a printk out of ftrace_raw_reg_event_foo()
    Date: Sun, 13 Dec 2009 14:08:04 +0100
    From: Li Zefan <lizf@cn.fujitsu.com>

    Move the printk from each ftrace_raw_reg_event_foo() to
    its caller ftrace_event_enable_disable(). This avoids each
    regfunc trace event callbacks to handle a same error report
    that can be carried from the caller.
