Christ. This one is too ugly to live.

I'm not pulling crap like this. It's f*^&ing stupid to take a lock, calculate a bitqueue, and just generally be an absolute ass-hat about things for waiting for a bit that is already set 99.999% of the time.

May I suggest just reverting that commit 250df6ed instead. It added all these insane things for no good reason. The comment said they are going away, but if they are just multiplying in ways like this, I really think the damn thing needs to be reverted. Any change that causes code like this is by definition not a good change.

You mean the part that removed smp_mb() on cleaning I_NEW? OK by me - definitely saner than what this variant is doing. AFAICS, evict() does _not_ need it - only unlock_new_inode(); in case of evict() the change of ->i_state is separated from that wake_up_bit() by spin_unlock followed by spin_lock and that ought to provide the barrier...

Done and pushed to the same branch;
