In the next few days I'll be submitting some further tty locking changes to the kernel. Line discipline ->write and ->read methods will no longer be covered by lock_kernel. For the moment tty->driver write methods won't change (that is they will be either lock_kernel or in an IRQ but never both). That is next on the hit list once the lock is driven out of the tty ldisc layer.
If you have any out of tree ldiscs please be ready. If you maintain any serial drivers still relying on lock_kernel for internal locking on the read/write paths, now would be a good time to fix them before they break
