This is just an internal API, that calls corresponding function in stream driver. This function will set @data = 1 if the underlying file is in data section, or @data = 0 if it is in a hole. At any rate, @length is set to number of bytes remaining in the section the file currently is. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
