tracing, kmemtrace: Make kmem 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 Signed-off-by: Zhao Lei <zhaolei@cn.fujitsu.com> Acked-by: Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Tom Zanussi <tzanussi@gmail.com> LKML-Reference: <49DEE6DA.80600@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
