    Subject[PATCH 7/9] PM: Fix pm_notifiers during user mode hibernation
    Date
    From: Andrey Borzenkov <arvidjaar@mail.ru>

    Snapshot device is opened with O_RDONLY during suspend and O_WRONLY durig
    resume. Make sure we also call notifiers with correct parameter telling
    them what we are really doing.
