KATO Takenori 18b4c8e206 Dirty change in union_lock(). Sometimes upper vnode is locked without ... UN_ULOCK flag. This shows a locking violation but I couldn't find the reason UN_ULOCK is not set or upper vnode is not unlocked. I added the code that detect this case and adjust un_flags. DIAGNOSTIC kernel doesn't adjust un_flags, but just panic here to help debug by kernel hackers.		1997-04-21 15:32:24 +00:00
