/sys/power/disk controls the operating mode of the suspend-to-disk
mechanism. Suspend-to-disk can be handled in several ways. We have a
few options for putting the system to sleep - using the platform driver
-(e.g. ACPI or other pm_ops), powering off the system or rebooting the
+(e.g. ACPI or other suspend_ops), powering off the system or rebooting the
system (for testing).
Additionally, /sys/power/disk can be used to turn on one of the two testing
