Subject: [PATCH 3/6] lightnvm: pblk: fix message if L2P MAP is in device

This usually happens if we are developing with qemu and ll2pmode has
default value. Even in that case message seems wrong.

You're right. This is inherited from rrpc.

Can we instead write "pblk: full host-side L2P table not supported"?
People will not know about the hybrid device/host L2P as time goes by
and it will just be confusing. I'm not even sure this will be part of
the 2.0 spec, so it will probably go away with time...

Sure. I was confused the first time. This is better.

It would be great if this is done while picking up. I can repost as
well if need be.
