patch 03/38: NFSv4 protocol header
From: Kendrick M. Smith <hidden>

lkml
Instantiate a new file, include/linux/nfs4.h, which contains constants and typedef's for the NFSv4 protocol (by analogy with include/linux/nfs2.h and include/linux/nfs3.h). Also #include this file in a few places where it will be needed later.
