Maybe a good place to do so is here, or in ufshpb_hpb_lu_prepared after you kicked the map work for pinned regions. Either way, If you decide to do so, I would appreciate if you could align to the framework I proposed in (scsi: ufshpb: Region inactivation in host mode). This way you would have a wrapper unmap_all that would call ufshpb_issue_umap_req with buffer id 0x3, And I would have a wrapper unmap_single that would call it with buffer id 0x1. Thanks, Avri
