Actually, multipathd could use TUR for checking unless we receive an

We wouldn't switch to the alua checker by default anyway, so the
vendors that prefer the sysfs prioritizer won't be hurt even
if that doesn't work.
Just one observation: currently there are ALUA arrays (NetApp E/EF, Dell Unity)
where their own checker is preferred.
As well as software-defined storage (Hitachi Vantara VSP One SDS Block, Linux-IO
(LIO) Target) where directio must be used.
