This read_cache_from() should be a noop, right, because it immediately
sees istate->initialized is set? So it shouldn't matter that it is not
in the conditional with discard_cache(). Though if its only purpose is
to re-read the just-discarded contents, perhaps it makes sense to put it
there for readability.
