Subject: [PATCH v2 1/4] ftrace, workqueuetrace: Make workqueue tracepoints use TRACE_EVENT macro
From: Zhao Lei <zhaolei@...fujitsu.com>
Subject: [PATCH v2] ftrace, workqueuetrace: Make workqueue tracepoints use TRACE_EVENT macro
TRACE_EVENT is a more generic way to define tracepoints.
Doing so adds these new capabilities to this tracepoint:
- zero-copy and per-cpu splice() tracing
- binary tracing without printf overhead
- structured logging records exposed under /debug/tracing/events
- trace events embedded in function tracer output and other plugins
- user-defined, per tracepoint filter expressions
Then, this patch convert DEFINE_TRACE to TRACE_EVENT in workqueue related tracepoint.
