This gets us back to my original objection. Can these things be unloaded? If not, and they get unconditionally all loaded up on the first DCCP connection, why make them seperate modules at all? If they can get unloaded, then you need synchronization. I would recommend that everything gets built into dccp.ko and thus the table is fixed and never changes and thus no locking nor any of this funny mod loading is needed at all. -- To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
