From f8fcd776212bcaa1e2359e39a43c1dbd752b8773 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Tue, 11 Sep 2012 01:14:58 +0300 Subject: perf tools: include wrapper for magic.h perf is currently including magic.h directly from the kernel. If the glibc magic.h is also included, this leads to warnings that the constants are redefined. This happens on some systems (e.g. Android). Redefinition errors on Android: In file included from util/util.h:79:0, from util/cache.h:5, from util/abspath.c:1: util/../../../include/linux/magic.h:5:0: error: "AFFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:53:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:19:0: error: "EFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:61:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:26:0: error: "HPFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:67:0: note: this is the location of the previous definition Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and SYSFS_MAGIC). This fix provides a wrapper for magic.h that includes only these constants instead of including the kernel header file directly.
