Hi Fiona, I sent an RFC series that calls io_poll_end() from the AioContext's home thread: https://lore.kernel.org/qemu-devel/20231213211544.1601971-1-stefa...@redhat.com/T/#t If you get a chance to test if it fixes the bug that would be great. It is based on my AioContext lock removal patch series: https://lore.kernel.org/qemu-devel/20231205182011.1976568-1-stefa...@redhat.com/ Thanks, Stefan
