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@xxxxxxxxxxxxxx/
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?
