This patch changes the NFSv3 xdr function to use xdr_decode_string for the
symlink target, which seems to be the easiest solution. I also considered
adding an additional parameter to vfs_symlink to pass the length, but that
requires changes in each and every filesystem and changes the VFS API.
That could be a task for 2.5.x.
