Look harder. It also moves the "detect a break" logic before
*status &= info->read_status_mask;
Apparently with the getty quintela uses, BRKINT isn't enabled, so SysRq "doesn't work" for him. I'm not sure it's a good idea to depend on userspace enabling BRKINT - in test6-pre5, sysrq_enabled affects serial SysRq as well.
