    Hibernation: Introduce system_entering_hibernation · abfe2d7b
    Rafael J. Wysocki 提交于
    Introduce boolean function system_entering_hibernation() returning
    'true' during the last phase of hibernation, in which devices are
    being put into low power states and the sleep state (for example,
    ACPI S4) is finally entered.
    
    Some device drivers need such a function to check if the system is
    in the final phase of hibernation.  In particular, some SATA drivers
    are going to use it for blacklisting systems in which the disks
    should not be spun down during the last phase of hibernation (the
    BIOS will do that anyway).
