There appears to some editing that’s done to make sure the code still compiles at least. On Raspbian between kernel 4.14 (about a year ago) and today’s kernel 4.19, the timer logic for delayed acks was removed, maybe because it used a kernel API which no longer exists. Unfortunately, the resulting system paniced as soon as one tried to create a logical link. (The removed code probably did change the implementation much since delayed ack is an optional feature in DECnet and Linux only implements a small part of it).
