I just referred to this function(L1266-L1321): static int maintenance_run_tasks(struct maintenance_run_opts *opts) { ... if (hold_lock_file_for_update(&lk, lock_path, LOCK_NO_DEREF) < 0) { ... free(lock_path); return 0; } free(lock_path); ... ... rollback_lock_file(&lk); return result; } and thought we should also apply it to "update_background_schedule()".
