Yes. But that should only cover "sleep_on()" and it's interruptible cousing "sleep_on_interruptible()". No other blocking call should have interrupts disabled, I would hope.
The special-case is a fairly specific "some old-style drivers avoid race conditions by having interrupts disabled over explicit conditional sleeps", not a generic "you may have interrupts disabled before blocking".
