3.13.11.8 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Filipe Brandenburger <[email protected]> commit bfcfd44cce2774f19daeb59fb4e43fc9aa80e7b8 upstream. The guard was introduced in commit ea1a8217b06b ("xattr: guard against simultaneous glibc header inclusion") but it is using #ifdef to check for a define that is either set to 1 or 0. Fix it to use #if instead. * Without this patch: $ { echo "#include <sys/xattr.h>"; echo "#include <linux/xattr.h>"; } | gcc -E -Iinclude/uapi - >/dev/null include/uapi/linux/xattr.h:19:0: warning: "XATTR_CREATE" redefined [enabled by default] #define XATTR_CREATE 0x1 /* set value, fail if attr already exists */ ^ /usr/include/x86_64-linux-gnu/sys/xattr.h:32:0: note: this is the location of the previous definition #define XATTR_CREATE XATTR_CREATE ^ * With this patch: $ { echo "#include <sys/xattr.h>"; echo "#include <linux/xattr.h>"; } | gcc -E -Iinclude/uapi - >/dev/null (no warnings) Signed-off-by: Filipe Brandenburger <[email protected]> Acked-by: Serge E.
