+static int ufshpb_issue_umap_all_req(struct ufshpb_lu *hpb)
Maybe ufshpb_issue_umap_all_req is just a wrapper for ufshpb_issue_umap_req?
e.g it calls ufshpb_issue_umap_req(hpb, int read_buferr_id = 0x3) ?
Then on host mode inactivation:
static int ufshpb_issue_umap_single_req(struct ufshpb_lu *hpb)
{
return ufshpb_issue_umap_req(hpb, 0x1);
}
