Some high-level comments: - Make sure your code can run on every platform supported by kcov (namely ARM64) - Check out Sashiko findings: https://sashiko.dev/#/patchset/20260603-kcov-dataflow-next-20260603-v2-0-fee0939de2c4%40est.tech, at least some of them seem to make sense - Please consolidate changes to the same file into a single patch - There seem to be two tools (one in C and one in Python) with overlapping functionality, can you keep only one? - The test modules seem to be used only in manual testing. Can you convert them to kselftests or remove them? - At this point, long dashes in the kernel codebase are quite rare, and I don't see a reason to add more.
