Sounds good, but doesn't this create other paths (e.g. initialization,
resume) where the ring is being accessed without holding the lock? Isn't
that a problem?
Thought about that also.
For init I'm pretty sure that no application can submit commands before
we are done, otherwise we are doomed anyway.
For resume I'm not really sure, but I think that applications are
resumed after the hardware driver had a chance of doing so.
