Merge branch 'nfs-for-2.6.37' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'nfs-for-2.6.37' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: net/sunrpc: Use static const char arrays nfs4: fix channel attribute sanity-checks NFSv4.1: Use more sensible names for 'initialize_mountpoint' NFSv4.1: pnfs: filelayout: add driver's LAYOUTGET and GETDEVICEINFO infrastructure NFSv4.1: pnfs: add LAYOUTGET and GETDEVICEINFO infrastructure NFS: client needs to maintain list of inodes with active layouts NFS: create and destroy inode's layout cache NFSv4.1: pnfs: filelayout: introduce minimal file layout driver NFSv4.1: pnfs: full mount/umount infrastructure NFS: set layout driver NFS: ask for layouttypes during v4 fsinfo call NFS: change stateid to be a union NFSv4.1: pnfsd, pnfs: protocol level pnfs constants SUNRPC: define xdr_decode_opaque_fixed NFSD: remove duplicate NFS4_STATEID_SIZE
