Thanks for the review!

This patch is here because when adding trace-related output in the
last patch (path 4), it was found that cachefiles_obj_[get|put]_ondemand_fd
did not have any relevant trace output, so it is added in this patch.
Putting it in the first patch may confuse the reader as to why it was
added, but it is easier to understand with cachefiles_obj_[get|put]_read_req
in front of it.
