Where's reparent_to_init in 2.6??

Does anybody know what the history is with the absence of the function reparent_to_init() in the 2.6 kernel? SLES 9.0 has it as an exported symbol but Suse 9.1 doesn't. Which is the wave of the future? Is the daemonize function supposed to be what is used instead? Any info, links or workarounds would be great. Thanks. Tim
