Have you verified that none of the ldisc methods rely on the big kernel
lock. In doing the tty audit I found several cases that tty drivers
still rely on this lock so I am curious why you make this change.

Would it not be better to fix the tty layer locking rather than
introduces new random memory corruptors ?
