[Qemu-devel] [RFC PATCH 0/9] Add support for io_uring

[Aarushi Mehta]

This patch series adds supports for the newly developed io_uring Linux AIO 
interface. Testing it requires a host kernel with it and the liburing library. 
Use the option -drive aio=io_uring to enable it.

Aarushi Mehta (9):
  qapi/block-core: add option for io_uring
  block/block: add BDRV flag for io_uring
  include/block: declare interfaces for io_uring
  stubs: add aio interface stubs for io_uring
  util/asyn: add aio interfaces for io_uring
  block/io_uring: implements interfaces for io_uring
  blockdev: accept io_uring as option
  block/file-posix: extends to use with io_uring
  configure: permits use of io_uring with probe
