Now, we can talk about making those sysfs core functions generate warnings
themselves, and we can talk about generating new wrappers around them which
generate warnings and which return void, then migrating code over to use
those.

If the only valid reason to fail is a kernel bug, it damn well should be 
that sysfs function itself that should complain. It's the only thing that 
knows and cares.

That's pretty much what Paulus and I have been advocating all along.

There -might- be a couple of cases where something has a good reason to
do a call that may fail and want to test the result code. For those few
rare cases (though none comes to mind at the moment), then I suppose we
could provide some kind of _try version of the function (or whatever you
want to call it) that doesn't warn and just returns an error.

But as I said, I can't see any such case out of the blue.

Cheers,
Ben.
