I 100% agree here. I haven't looked at how the data gets stored, but it should definitely be consistent across kernels. Maybe store metadata in the persistent storage that explains how to parse the binary data? Similar to /debug/tracing/events/ftrace/function/format is done. -- Steve _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
