NFS: Fix an Oops in encode_lookup()
It doesn't look as if the NFS file name limit is being initialised correctly in the struct nfs_server. Make sure that we limit whatever is being set in nfs_probe_fsinfo() and nfs_init_server(). Also ensure that readdirplus and nfs4_path_walk respect our file name limits. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
