    Subject[PATCH 2/2] PM: Use the freezer_count() functions in [un]lock_system_sleep() APIs
    Date
    Now that freezer_count() and freezer_do_not_count() don't have the restriction
    that they are effective only when called by userspace processes, use
    them in lock_system_sleep() and unlock_system_sleep() instead of open-coding
    their parts.
