The zone block support all looks pretty neat, but I think you're making
this harder than necessary to support streams. You don't need to treat
these like a sequential write device. The controller side does its own
garbage collection, so no need to duplicate the effort on the host. And
it looks like the host side gc potentially merges multiple streams into
a single gc stream, so that's probably not desirable.
