Please, no.

This would mean that 'tpg_pref' would evaluate the PREF bit _only_,
with total disregard to the other settings.

We should be updating the existing 'alua' prioritizer to evaluate
the PREF bit together with the existing AAS status; then we could
be using it for all scenarios.

I think I got a patch somewhere ...

Cheers,
