Ah-hahh.

I've had this slightly smaller patch waiting for the better part of a year:

https://lore.kernel.org/lkml/CAHk-=wgjR7Nd4CyDoi3SH9kPJp_Td9S-hhFJZMqvp6GS1Ww8eg@mail.gmail.com/

waiting to see if some broken program actually depends on the bogus
epollet semantics.

Can you verify that that patch fixes the realm-core brokenness too?
