From 82ef04fb4c82542b3eda81cca461f0594ce9cd0b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 31 Jul 2008 17:02:40 +0900 Subject: libata: make SCR access ops per-link Logically, SCR access ops should take @link; however, there was no compelling reason to convert all SCR access ops when adding @link abstraction as there's one-to-one mapping between a port and a non-PMP link. However, that assumption won't hold anymore with the scheduled addition of slave link. Make SCR access ops per-link.
