I don't see how this is related to the rest of the seris. I also don't
think it's a good idea. The APIs isn't deprecated per se. It just
should not be called by drivers. The right thing would be an interface
EXPORT_SYMBOL_GPL_FOR(bdev_disk_changed, loop.ko, CONFIG_BLK_DEV_LOOP);
EXPORT_SYMBOL_GPL_FOR(bdev_disk_changed, dasd_mod.ko, CONFIG_DASD);
with the modulo code enforcing that no one but the module this is
explicitly exorted for can use the symbol.
