Yeah, because they're pretty different things:
- PREEMPT_RT is roughly a scheduler setting and barely has much do with real-time and so ought to be renamed.
- On the other hand an actual real-time OS would have either timebound calls (say via timeouts) or non-blocking calls. This means you programs simply *cannot* be frozen due to I/Os or the network being suddenly slow.
