This is starting to look better and better. I wouldn't be sad if it was
merged like this, but the locking still looks a little bit wacky to me,
and it's not 100% clear what priv->mm_lock protects and what it doesn't.
I can make a breakdown of how each member of fpe_cfg is used, and thus
understand exactly what are the locking needs and how they are addressed
in this version, but most likely not today.
