For store_info?  I don't think that's a good idea - most users of
store_info should really be converted to sysfs insead, but this
would break all kinds of existing apps.  So we should add it but not
rip out the procfs support.  Mixing up procfs and sysfs code isn't
a good idea anyway - this will lead to overloaded APIs again.
