Note, I took this because it mentioned:

"Commit
       9652dc2eb9e40 ("tcp: relax listening_hash operations")
    
    removed the need to disable bottom half while acquiring
    listening_hash.lock. There are still two callers left which disable
    bottom half before the lock is acquired."

And that commit was added in 4.10.

I will remove it and release a rc2.

Thanks!
