The patch looks good, but I have a question. If a target implements the
scalar interface, then it will not be limited to 64 lbas/ppas and it
will not make sense to split the bio base don this value. In fact, it
looks like in time, we will move to a scalar interface in the 2.0 path
to align with the zoned interface, so this value will be dependent on
whether the target is using the scalar or vector interface.
