noreply@ellerman.id.au reported a similar failure for m5272c3_defconfig,
which I have bisected to commit 261187e66de362de ("io_uring: pass in
EPOLL_URING_WAKE for eventfd signaling and wakeups").  That patch
does not seem to have been posted to a public mailing list archived by lore?
Oh, it was, but using a different subject
https://lore.kernel.org/all/20221120172807.358868-4-axboe@kernel.dk
Difficult to track without a Links: tag...

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
