From 5ad960fe8d0e4f99fe2b8dded45e8251137293c9 Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@kernel.org> Date: Sun, 19 Apr 2009 08:46:03 +0900 Subject: ide: drop rq->data handling from ide_map_sg() Impact: remove code path which is no longer necessary All IDE data transfers now use rq->bio. Simplify ide_map_sg() accordingly.
