Date: Mon, 4 Nov 2013 19:52:59 -0500 From: Phillip Susi <psusi@...ntu.com> To: linux-scsi@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 1/2] libata: use sleep instead of standby command The ATA SLEEP mode saves some more power than SUSPEND, and has basically the same recovery time, so use it instead.
