From d6a7bbdde67227127e5e33fb9500bcc4abc40fb3 Mon Sep 17 00:00:00 2001 From: Kassey Li Date: Fri, 8 Mar 2024 10:18:18 +0800 Subject: workqueue: add function in event of workqueue_activate_work The trace event "workqueue_activate_work" only print work struct. However, function is the region of interest in a full sequence of work. Current workqueue_activate_work trace event output: workqueue_activate_work: work struct ffffff88b4a0f450 With this change, workqueue_activate_work will print the function name, align with workqueue_queue_work/execute_start/execute_end event. workqueue_activate_work: work struct ffffff80413a78b8 function=vmstat_update Signed-off-by: Kassey Li Reviewed-by: Steven Rostedt (Google) Signed-off-by: Tejun Heo --- include/trace/events/workqueue.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'include/trace/events') diff --git a/include/trace/events/workqueue.h b/include/trace/events/workqueue.h index 262d52021c23..6ef5b7254070 100644 --- a/include/trace/events/workqueue.h +++ b/include/trace/events/workqueue.h @@ -64,13 +64,15 @@ TRACE_EVENT(workqueue_activate_work, TP_STRUCT__entry( __field( void *, work ) + __field( void *, function) ), TP_fast_assign( __entry->work = work; + __entry->function = work->func; ), - TP_printk("work struct %p", __entry->work) + TP_printk("work struct %p function=%ps ", __entry->work, __entry->function) ); /** -- cgit v1.2.3
