The filesystem lookup gets a dentry with a valid parent pointer, so it
could use that to access the true parent. Though perhaps it would be
better to export a parent() function, rather than have the fs looking
inside the structure.

Hopefully this patch will clear up the oops reports in kswapd and
sys_newstat.
