deprication warning using -a mdp

Dear List

I just saw a deprication warning on a new system creating a RAID1 with

	mdadm --create /dev/mdX --auto=mdp ...

Could you please tell me whether support for creation and handling of partitionable whole disk md raids will stop in the future?

Regards, Adrian.

Is the deprication warning using

	--auto=mdp 

meant for the switch --auto itself or is it meant that partitionable RAIDs won't be supported any more in the future? If the latter is the case, what is the migration path for users like me that use this feature extensively on many machines?

Thank you for your answers.

Regatds, Adrian.
