Industry seems to think otherwise.

That still isn't a match for something like INTEGRITY OS, vxWorks, QNX when human lives are at risk.

Or why despite using an heavily modified Linux kernel as basis for Azure Sphere, Microsoft rather advocates Azure RTOS for real time tasks.

Or why the Linux Foundation, ironically pushes Zephyr for such purposes, completely unrelated to Linux source code.

If Linux with PREEMPT_RT is unsuitable, all the modern x86 CPUs with system management mode interrupts are even worse. Because those are the worst and primary cause for that Linux being insufficient for control loops in the 10's of kHz.
