> On LibAIO is possible to retrieve the I/O completion events without
> using io_getevents sys-calls by reading the user-space ring buffer used by the
> kernel to store them.
> This is already beneficial for very fast disks and necessary for further
> improvements
> of ASYNCIO Journal to leverage (very) fast low-latency disks by going
> completly
> lock-free.
