Merge tag 'trace-fixes-v3.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fix from Steven Rostedt: "Masami Hiramatsu fixed another bug. This time returning a proper result in event_enable_func(). After checking the return status of try_module_get(), it returned the status of try_module_get(). But try_module_get() returns 0 on failure, which is success for event_enable_func()" * tag 'trace-fixes-v3.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Return -EBUSY when event_enable_func() fails to get module
