They certainly can, but should they?  There may be some reason to prefer
sysfs that should be self-evident - except that I'm a bit thick and seem
to need it spelled out.  Or maybe I've just become disillusioned with
the practice of replacing crappy interfaces (ioctl here) with other
crappy interfaces (sysfs here) and having to support both for all
eternity.  sysctl, ioctl, proc, sysfs, debugfs, netlink, ... -
individually they all suck in their own peculiar way.  But together they
create a mess I no longer dare to name.

So what was the reason again why mtd needs two userspace interfaces
instead of just one?
