FWIW, in iwlwifi I made the data portion (only!) a separate tracing subsystem, so that you can do trace-cmd record -e iwlwifi to get the hdrs, and trace-cmd record -e iwlwifi -e iwlwifi_data to get the hdrs, and the data, and then I put the two together in userspace. That way, "-e iwlwifi" gets most useful stuff, and adding -e iwlwifi_data when needed still has no duplication. With what you're suggesting, it will be difficult to control tracing to do exactly what's needed. Anyway, I don't really care, but this just caught my eye. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
