Speaking about drivers specifically, a controlling miscdev, one per
device or one per group of devices depending on your needs, is a much
more clean solution for passing ioctl-type data. You are free to come
up with whatever method of communication with the driver is most
efficient for your needs -- without perverting open(2).
Notice also a "metadata miscdev" solves the problem of passing options
on open -- just pass those options to the miscdev before you open it...
metadata miscdevs are a clean solution to what procfs hacks and ioctls
are trying to accomplish.
