That is cute, but no, the kernel does NOT provide built-in help texts
for sysfs files. If you know of any existing ones that do this, please
point them out to me and I will go delete them from the tree.
sysfs is "one value per file", and a "multi-line-help-text" is not a
single value.
That is what the Documentation/ABI files are for, which I do not see an
update for in this patch so I can not take it, sorry :(
thanks,
