In Linux, when a real time process is executing and an interrupt comes, will
the RT process be preempted?
Is RT process considered superior to interrupts?
Generally, interrupts always intercept processes as long as interrupts are
enabled, but ...
A missed IRQ is not considered fatal but
A missed IRQ is not considered fatal but where as missing the upper time
limit for an RT process will be considered fatal. Hence I think, as a
simple solution, the process should not be preempted.
Is it the case?

Are you *sure* that ignoring an IRQ for an arbitrarily long time is non-fatal?
(Hint - it may not be fatal to the *kernel*. Think bigger)
limit for an RT process

Think it through - that would imply that RT processes effectively run with
interrupts
