From cd44f09a52abe440cfb2cbfd03f8ea35565f8750 Mon Sep 17 00:00:00 2001
From: Mike Frysinger <vapier@gentoo.org>

Subject: [PATCH 4/9] linux/stddef.h: export offsetof() to userspace
Some userspace headers (like fuse.h) utilize the offsetof() macro. Some
userspace packages (like lkcd) expect linux/stddef.h to provide this as
well.
