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 like 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.

Jessh, sorry it is too late here and that was a typo that the commit went into the series. I'll go sleep now. This I just had queued as a reminder for the new annotation for deprecated symbols to be used in some situations. Please ignore this patch. Luis

This ensures no other users pop up by mistake easily and provides us a with an easy vehicle to do the same with other routines should we need it later.
