Oops, I forgot that the SYSCTL macros hid the use of linker sets when John
asked me about this.  Perhaps you should implement sysctl again :-).
Something needs to be done anyway to support it in LKMs and fix it
in vfs's.  One idea: attach everything to one linker set and encode the
tree structure in the oid struct.  I think this doesn't lose anything
except possibly space.
