Winsock Registered I/O or RIO predates io_uring and you could make the argument that io_uring "is largely a copy-paste of RIO" if you wanted to be childish.
The truth is that they both use a obvious pattern of high-performance data transfer that's been around a long time. As I said, NVME devices have been doing that for a while and it's a common paradigm in any DMA-based transfer.
io_uring seems more expansive and hence useful compared to the limited scope of RIO or even the NtIoRing stuff.

This was unnecessary. I'm not denigrating I/O Rings or io_uring. The NT kernel is more advanced than the Linux/BSD/macOS kernels in certain ways. There should be a back-and-forth copying of the good ideas/implementations.
