Not that I've seen. I'm fixing some locking but not stuff that depends on lock_kernel(). In the meantime therefore it seems inappropriate to add random corruptors and bugs to the kernel in pursuit of low latency other than as private "add this but beware" patches.
The tty I/O patches should not be applied until the tty layer doesn't rely on the lock_kernel locking. So if people want the low latency stuff covering the tty code I suggest that rather than making other peoples machines crash more, they volunteer. The console driver might be a good starting point.
