Any new sysfs file (or removal or modification) also requires a matching
Documentation/ABI/ file as well.  Please include it in this patch (if it
ends up surviving...)

I didn't like that one, it was wrong and I also think you caused a
reference count issue by adding a kobject to that structure...

Why change the name of this function?  You now have a function, field,
and sysfs file with that same name, talk about a way to cause confusion
