The patch doesn't fit my kernel. My cliet.c looks a little bit different from the client.c in the patch:

if (server->wsize > NFS_MAX_FILE_IO_SIZE)
                server->wsize = NFS_MAX_FILE_IO_SIZE;
        server->wpages = (server->wsize + PAGE_CACHE_SIZE - 1) >> PAGE_CACHE_SHIFT;
        server->pnfs_blksize = fsinfo->blksize;
        set_pnfs_layoutdriver(server, mntfh, fsinfo->layouttype);

        server->wtmult = nfs_block_bits(fsinfo->wtmult, NULL);

The same thing on nfs4proc.c:
{
        nfs_fattr_init(fsinfo->fattr);
        return nfs4_do_fsinfo(server, fhandle, fsinfo);
}

there is no error routine or if-statement like in the patch.
that was a different kernel i tried, kernel-3.3.0-0.rc2.git1.1.pnfsd.fc17.src.rpm from http://steved.fedorapeople.org/repos/pnfs

Thats the complete output from dmesg after mounting and try to create a file (i think thats only nfsv4):
