From 0ce3a7e5bd305e96c924fab1e3126480c665f017 Mon Sep 17 00:00:00 2001 From: Brian King Date: Fri, 11 Jul 2008 13:37:50 -0500 Subject: [SCSI] ipr: Fix HDIO_GET_IDENTITY oops for SATA devices Currently, ipr does not support HDIO_GET_IDENTITY to SATA devices. An oops occurs if userspace attempts to send the command. Since hald issues the command, ensure we fail the ioctl in ipr. This is a temporary solution to the oops. Once the ipr libata EH conversion is upstream, ipr will fully support HDIO_GET_IDENTITY.
