This statement is obviously not true :-( Let us start in a way that makes sense: Please send me the whitepaper that was used to define the interfaces and functionality of the /sys device Please send me the other documentation (e.g. man pages) on the /sys device Please send me a statement on how long this interface will be maintained inside Linux without breaking interfaces.
