This is a nit, but there is no lpc_write_module_reloc. It should be
klp_write_module_reloc.
Indeed. Michael, feel free to fix this on the fly or not. It needs to
disappear anyway and be replaced with functionality.
Or not at all thanks to Jessica's effort [1].

Miroslav, thanks for the CC. Indeed, if things go well, there may be
no need to implement klp_write_module_reloc() anymore in the near
future. :-)
