From: NeilBrown <neilb@xxxxxxx> commit 6c0f5898836c05c6d850a750ed7940ba29e4e6c5 upstream. When BLOCK_LEGACY_AUTOLOAD is not enable, mdadm is not able to activate new arrays unless "CREATE names=yes" appears in mdadm.conf As this is a regression we need to always enable BLOCK_LEGACY_AUTOLOAD for when MD is selected - at least until mdadm is updated and the updates widely available.
