Our project really needs a fix to this issue

Could you be more specific why? My understanding is that RT tasks
usually have all the memory mlocked otherwise all the real time
expectations are gone already.

The RT thread is created by a process with normal priority, and the process was sleep, 
then some task needs the RT thread to do something, so the process create this thread, and set it to RT policy.
I think that is the reason why RT task would read the swap.
