When interfacing we must make sure that ccid3 tfrc_lh_slab is created
and then tfrc_li_cachep is not needed. I'm doing this while keeping
the structure of the patches, i.e. one introducing, the other removing.
But we need to create tfrc_lh_slab if we want the tree to be bisectable.

I'm doing this and keeping your Signed-off-line, please holler if you
disagree for some reason.
