why can't we?
Because it would newer call cond_resched() in non-preemptive kernel
with CONFIG_PREEMPT_COUNT disabled. IMHO, we want to call it,
for example, when we scroll the entire screen from tty_operations.
Or do I miss anything?
so... basically. it has never called cond_resched() there. right?
why is this suddenly a problem now?
