DESCRIPTION

19       Meta-devices like DM and MD need to verify that all sub-devices use the
20       same integrity format before advertising to upper layers that they can
21       send/receive integrity metadata. This function can be used to check
22       whether two gendisk devices have compatible integrity formats.
