From f7913971bdad1a72c6158074786babed477d61e2 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 29 Jan 2015 17:06:45 +0900 Subject: [PATCH] perf header: Set header version correctly When check_magic_endian() is called, it checks the magic number in the perf data file to determine version and endianness. But if it uses a same endian the verison number wasn't updated and makes confusion.
