From 9efc6c29b9bed6c054978068c078dc142b90609a Mon Sep 17 00:00:00 2001
From: Mike Frysinger <vapier@gentoo.org>
Date: Sat, 27 Dec 2008 01:11:46 -0500
Subject: [PATCH] linux/uio.h: cleanup for userspace
Hide iov_shorten() behind __KERNEL__ since it's a prototype only. Use the
__inline__ form for iov_length() since it's usable by userspace.
