Alan,

I am very sorry, but I don't see it. We didn't held the lock while 
calling tty_audit_push() before, and we don't hold it after the patch 
neither.
So what's the locking scheme change here? Is there some binding between 
n_tty_read() and tty_audit_push() I just don't see?

Thank you,
-Stanislav
