From 15c73d5afd9f7489ca6a71cd0bef60f94c0c85a8 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 26 Mar 2008 09:26:13 -0700 Subject: [PATCH] [SCSI] libsas: Warn if ATA device detected but CONFIG_SCSI_SAS_ATA not set We give a very cryptic error if an ATA device is seen on a SAS port but libsas isn't compiled to include libata to handle them. Add an extra warning to explain specifically what the problem is. Acked-by: Darrick J.
