Date: Wed, 2 Oct 2013 21:05:31 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Vinson Lee <vlee@...tter.com>, Borislav Petkov <bp@...e.de>, Vinson Lee <vlee@...edesktop.org>, Arnaldo Carvalho de Melo <acme@...hat.com> Subject: [ 13/52] tools lib lk: Uninclude linux/magic.h in debugfs.c 3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Vinson Lee <vlee@...tter.com> commit ce7eebe5c3deef8e19c177c24ee75843256e69ca upstream. The compilation only looks for linux/magic.h from the default include paths, which does not include the source tree. This results in a build error if linux/magic.h is not available or not installed. For example, this build error occurs on CentOS 5. $ make -C tools/lib/lk V=1 [...] gcc -o debugfs.o -c -ggdb3 -Wall -Wextra -std=gnu99 -Werror -O6 -D_FORTIFY_SOURCE=2 -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k -Winit-self -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wno-system-headers -Wold-style-definition -Wpacked -Wredundant-decls -Wshadow -Wstrict-aliasing=3 -Wstrict-prototypes -Wswitch-default -Wswitch-enum -Wundef -Wwrite-strings -Wformat -fPIC -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 debugfs.c debugfs.c:8:25: error: linux/magic.h: No such file or directory The only symbol from linux/magic.h needed by debugfs.c is DEBUGFS_MAGIC, and that is already defined in debugfs.h. linux/magic.h isn't providing any extra symbols and can unincluded. This is similar to the approach by perf, which has its own magic.h wrapper at tools/perf/util/include/linux/magic.h Signed-off-by: Vinson Lee <vlee@...tter.com> Acked-by: Borislav Petkov <bp@...e.de> Cc: Borislav Petkov <bp@...e.de> Cc: Vinson Lee <vlee@...edesktop.org> Link: http://lkml.kernel.org/r/1379546200-17028-1-git-send-email-vlee@freedesktop.org Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@...uxfoundation.org> --- tools/lib/lk/debugfs.c | 1 - 1 file changed, 1 deletion(-) --- a/tools/lib/lk/debugfs.c +++ b/tools/lib/lk/debugfs.c @@ -5,7 +5,6 @@ #include <stdbool.h> #include <sys/vfs.h> #include <sys/mount.h> -#include <linux/magic.h> #include <linux/kernel.h> #include "debugfs.h" -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
