From 9666f4009c22f6520ac3fb8a19c9e32ab973e828 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 4 May 2007 21:27:47 +0200 Subject: libata: reimplement suspend/resume support using sdev->manage_start_stop Reimplement suspend/resume support using sdev->manage_start_stop. * Device suspend/resume is now SCSI layer's responsibility and the code is simplified a lot. * DPM is dropped. This also simplifies code a lot. Suspend/resume status is port-wide now. * ata_scsi_device_suspend/resume() and ata_dev_ready() removed. * Resume now has to wait for disk to spin up before proceeding. I couldn't find easy way out as libata is in EH waiting for the disk to be ready and sd is waiting for EH to complete to issue START_STOP. * sdev->manage_start_stop is set to 1 in ata_scsi_slave_config(). This fixes spindown on shutdown and suspend-to-disk.
