Perhaps we should just not do this in sysfs at all but in debugfs? We have a
lot more freedom there. No requirement of one-value-per-file, and if we need
to we can change things in the future. It would actually be easier to issue

I tend to agree with Hans. We've already got *too many* interfaces
that do the same thing. The testing matrix is already a nightmare -

extended controls, and don't get

how about security permissions? while you can easily change the
permission levels for nodes in /dev you can't do this so easily with
sysfs entries.
I don't really think this is needed at all some applications will
start to use ioctl

Hi all,
The new control framework makes it very easy to expose controls in sysfs.
The way it is implemented now in the framework is that each device node
will get a 'controls' subdirectory in sysfs. Below which are all the controls
associated with that device node.
So different device nodes can
