Hello,

Could you provide a bit more information on your query here please? Its not obvious what the issue is.

uring command[1] is added to linux kernel v5.20, and it aims at fast userspace storage, such as:

3. maybe more

However tokio-uring doesn't export such OP, so I raise this issue, and I guess it shouldn't be very hard to add such feature.

Thanks,
