    dm integrity: flush the journal on suspend
    
    [ Upstream commit 5e5dab5ec763d600fe0a67837dd9155bdc42f961 ]
    
    This commit flushes the journal on suspend. It is prerequisite for the
    next commit that enables activating dm integrity devices in read-only mode.
    
    Note that we deliberately didn't flush the journal on suspend, so that the
    journal replay code would be tested. However, the dm-integrity code is 5
    years old now, so that journal replay is well-tested, and we can make this
    change now.
