The src_offset parameter isn't used in this function.

In early versions of the series, it was used to feed the p->start_offset
field of each load_cache_entries_thread_data. But after the switch to
ieot, we don't, and instead feed p->ieot_start. But we always begin that
at 0.

Is that right (and we can drop the parameter), or should this logic:

> +	for (i = 0; i < nr_threads; i++) {

be starting at src_offset instead of 0?
