Is the wrong fix. "internal.h" should not be included more than once per C
file. One of the C files has acquired two inclusions of "internal.h",
probably due to a git merge tool error.
I've given Trond the attached patch to fix things up. Note the change to
nfs2xdr.c.

[PATCH] NFS: Fix up split of fs/nfs/inode.c
From: David Howells <dhowells@redhat.com>
Fix ups for the splitting of the superblock stuff out of fs/nfs/inode.c,
including:
(*) Move the callback tcpport module param into callback.c.
(*) Move the idmap cache timeout module param into idmap.c.
(*) Changes to internal.h:
(*) namespace-nfs4.c was renamed to nfs4namespace.c.
(*) nfs_stat_to_errno() is in nfs2xdr.c, not nfs4xdr.c.
(*) nfs4xdr.c is contingent on CONFIG_NFS_V4.
(*) nfs4_path() is only uses if CONFIG_NFS_V4 is set.
(*) nfs2xdr.c shouldn't include internal.h twice.
Plus also:
(*) The sec_flavours[] table should really be const.
(*) A bit seems to have been lost from the changes to nfs_clear_inode(). The
BUG_ON() was replaced with nfs_wb_all().
!!! This needs checking by Trond !!!
