kthread: save thread function
It's handy to keep the kthread_fn just as a unique cookie to identify
classes of kthreads. E.g. if you can verify that a given task is
running your thread_fn, then you may know what sort of type kthread_data
points to.
We'll use this in nfsd to pass some information into the vfs. Note it
will need kthread_data() exported too.
