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:

[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/io_uring/uring_cmd.c

1) xnvme

https://xnvme.io/

2) ublk

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,
