From b91421749a1840148d8c81637c03c0ace3f35269 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 22 Jul 2007 13:15:55 -0500 Subject: [SCSI] libsas: make ATA functions selectable by a config option Not everyone wants libsas automatically to pull in libata. This patch makes the behaviour configurable, so you can build libsas with or without ATA support.
