From e52dcc4899cf1b7601379c31542bd91cd2997a64 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 2 Apr 2008 17:35:19 +0900 Subject: libata: ATA_12/16 doesn't fall into ATAPI_MISC SAT passthrus don't really fit into ATAPI_MISC class. SAT passthru commands always transfer multiple of 512 bytes and variable length response is not allowed. This patch creates a separate category - ATAPI_PASS_THRU - for these. This fixes HSM violation on "hdparm -I".
