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.
