Subject: RE: [PATCH v2 5/5] scsi: ufs: UFS Host Performance Booster(HPB)

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.
