I can put an RFC together in few days. My plan is to borrow as much as possible from Samsung driver, But to move the L2P cache management and HPB-READ command setup to the scsi mid-layer. Also maybe elaborate the host-managed mode logic to some extent. This will not be a full-fledged driver, but more of a skeleton - The gory details can come after, once we'll agree on the general concept. Let's wait few days more to allow some more people to comment. Ideally, this should be a joint effort of the ufs community, Given the size of this driver, and the industry's interest and focus. Thanks, Avri
