This could be your problem. real_lookup assumes that if you return
anything it is a new dentry that you found in some magical way and drops
the refcount on the old dentry (which happens to be the one you are
returning). If the refcount drops to zero the dentry is up for grabs
at which point you've lost any sanity in the kernel's data structures.

  zanx for the hint. and don't cc: me, I'm subscribed to the list.
