No idea - it looks like dkpg was trying to remove a directory on the same path the lookup was and both have gone splat in __d_lookup on the same dentry. Something happened in those 180 days that left a landmine that was tripped over here, I think. I can't see any way of tracking it down from this, but thanks for reporting it anyway, Justin.

No idea - it looks like dkpg was trying to remove a directory on the same path the lookup was and both have gone splat in __d_lookup on the same dentry. Something happened in those 180 days that left a landmine that was tripped over here, I think. I can't see any way of tracking it down from this, but thanks for reporting it anyway, Justin.
