Linux 3.14 compat: rq_for_each_segment in dmu_req_copy
rq_for_each_segment changed from taking bio_vec * to taking bio_vec. We provide rq_for_each_segment4 which takes both. Signed-off-by: Chunwei Chen <[email protected]> Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Issue #2124
