From 723928340c9d28d92dcaff8b8fbc9100a1cf9429 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 24 Dec 2015 11:16:17 +0900 Subject: [PATCH] perf hist: Save raw_data/size for tracepoint events The raw_data and raw_size fields are to provide tracepoint specific information. They will be used by dynamic sort keys later.
