As Andrew correctly pointed out, this bit error is not a RAM problem.
It is actually the low bit of a counter a spinlock that was
decremented just before the WARN_ON. So it simply indicates that the
inode had already been freed, which I think we knew already.

Unfortunately I still have no idea why that inode had been
freed but was still referenced by a dentry....

How repeatable as this bug? How did you narrow it down to that patch?
Did you use git-bisect or something else?


Thanks,
