From 5698d2c99ec11006b4c241ebad5252289902b358 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Wed, 17 Jul 2013 17:08:15 +0900 Subject: [PATCH] perf symbols: Do not apply symfs for an absolute vmlinux path If an user gives both of --symfs and --vmlinux option, the vmlinux will be searched under the symfs directory. This is somewhat confusing since vmlinux often lives in kernel build directory or somewhere other than user space binaries. So it'd be better not adding symfs prefix for a vmlinux if it has an absolute pathname.
