[PATCH v3] linux/uio.h: cleanup for userspace

From: Mike Frysinger
Date: Mon Dec 29 2008 - 08:00:40 EST


Hide iov_shorten() behind __KERNEL__ since it's a prototype only. Use the
__inline__ form for iov_length() since it's usable by userspace.

v3
- keep all __KERNEL__ stuff in one place
v2
- drop inline conversion stuff
