Also, we're thinking that some operations require that you first "acquire
ownership" of the respective device, which I believe maps more easily to
open() and ioctls than sysfs.

Thanks

Yes, sysfs doesn't implement open/close so there's no clean way to
have one thing in userspace that owns the interface.  It's a shame.

No, that was by design :)

Well that's good to know!  linux-api is copied on this patchset.  I'm
wondering if there is another mailing list that can weigh in on this
new ioctl that is being added to the kernel or if that's the one.
