Hmm...a brief look at the Arch Linux package source suggests QEMU is
not being built with io_uring enabled. Anatol, please confirm whether
this is correct.
If io_uring is not enabled then this bug may affect most existing
users on Linux. Initially I thought it was because Arch Linux had
enabled the new io_uring feature but I was probably mistaken.
