According to the patch itself, the broken commit was 3f5fe9fef5b2 ("sched/debug: Fix task state recording/printout") which was merged at what looks like 4.15-rc2. The broken commit was also picked for 4.14.64 as 13f12749af15 ("sched/debug: Fix task state recording/printout"). The fix (3054426dc68e) was pulled into 4.19. but was not called out as needing to go back to 4.14. > > > > > > Is it possible to pick 3054426dc68e ("sched, trace: Fix prev_state output in sched_switch tracepoint") for the next stable 4.14 release?
