I'm unconvinced that it is any cheaper. The question is ... how is
the kernel DDI going to track these by dev_t. dev_ts don't point to
structures. So the DDI implementation would either need to use a
hash table itself, or would need to manage to track the state
elsewhere, and I'm just not sure where it would be tracked. We need
more information about the proposed underlying implementation, I think.
The DDI doesn't have to track anything. The dev_ts are managed by
specfs which has access to the underlying vnode or snode - hence my
comment about stashing the context pointer there.

In this case, yes, sparing the table lookups would indeed be faster.
