Thanks for the prompt reply. Should I file it on bugzilla? Just as a
reminder, the first problematic commit is
fa27271bc8d230355c1f24ddea103824fdc12de6: genirq: Fixup poll handling

As the MAINTAINERS file only lists Thomas as the responsible for the
IRQ subsystem, I'm still CC'ing linux-kernel, but I can bring the
discussion to any other mailing list, if applicable.


Thanks,
