Well honestly I think I would rather have a spin lock then an rcu thing.

It may not be a big deal because we already have to check the count and
if it is zero ignore the namespace, so rcu may not add complications but
changing something that already has interesting usage and lifetime rules
to rcu sends up warning signs for me.
