syzbot ci: continuous patch series fuzzing
summary
syzbot ci is a prototype that shifts fuzzing left by monitoring kernel mailing lists, automatically applies patch series to an inferred base tree, and runs targeted coverage‑guided fuzzing (syzkaller backend) on the modified code paths. From ~7,000 series processed it skips ~13% that don’t apply, 37% get 3 hours of focused fuzzing, and the pilot has reported 105 findings to patch threads so far. Reproducer‑based triage filters preexisting bugs; base‑tree detection and coverage limits are current pain points.
