Sorry, its not obvious where show_regs_print_info() prints this. dump_stack_print_info() itself doesn't directly. print_worker_info() doesn't. print_stop_info() doesn't. Not sure whether print_scx_info() does. Maybe showing example output would help? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
