See http://www.infradead.org/rpr.html The md driver wants to enforce a number of flags to an all devices, even when not inheriting them from the underlying devices. To make sure these flags survive the queue_limits_set calls that md uses to update the queue limits without deriving them form the previous limits add a new md_init_stacking_limits helper that calls blk_set_stacking_limits and sets these flags.
