From 40a1d531f6c894b298e784fd2090d87633e4989a Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 27 Jun 2007 02:49:38 +0900 Subject: [PATCH] libata: kill ATA_HORKAGE_DMA_RW_ONLY ATA_HORKAGE_DMA_RW_ONLY for TORiSAN is verified to be subset of using DMA for ATAPI commands which aren't aligned to 16 bytes. As libata now doesn't use DMA for unaligned ATAPI commands, the horkage is redundant. Kill it.
