How does that work? module.c does the register/deregister on behalf of the module? I certainly encourage people to disagreee with me here, but my current thinking is: - the cleanup aspect isn't worth the runtime overhead and - the support-modular-users aspect is largely new and would need a lot more description and justification (with examples) before we can even begin to evaluate it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
