A drive that is in standby simply treats these commands as a NOOP. One that is in SLEEP can not do that, so we must do it for the drive. Without this patch, SLEEP mode is basically useless since the drive will be woken up by one of these commands quite soon after you put it to SLEEP. This is just to make hdparm -Y not useless. It has nothing to do with suspend/resume. I was thinking of splitting this patch series into two parts, one with just the patches related to SLEEP and one with the patches related to suspend/resume.
