The set contains two fixes for direct packet access range markings and test cases for all direct packet access patterns that the verifier matches on. They are targeted for net tree, note that once net gets merged into net-next, there will be a minor merge conflict due to signature change of the function find_good_pkt_pointers() as well as data_meta patterns present in net-next tree. You can just add bool false to the data_meta patterns and I will follow-up with properly converting the patterns for data_meta in a similar way. Thanks a lot!
