+ qemu: support io mode io_uring to libvirt
... async IO mode 'io_uring' in libvirt
+ </summary>
+ <description>
+ From Linux 5.1 and QEMU 5.0.0, the io_uring aio interface was
+ introduced. Implement that to libvirt with the io value 'io_uring'.
I'd expect some description of what the new backend provides:
Add support for the 'io_uring' mode for asynchronous I/O introduced in
QEMU 5.0 which is designed to improve performance. (Requires at least
Linux 5.1).
Or something along that.
