[TNTWEN]

Hello! Thanks for your great work!
I have make this project successfully,but when running ./uring_echo_server,error happens like this:

Kernel version: 5.15.0-67-generic
./uring_echo_server: io_uring_register_buf_ring: Invalid argument

I want to know how to solve this problem，Thanks！

Hey,

This is most likely a problem with your kernel version. For e.g. io_uring_register_buf_ring you need a version >= 5.19:
https://man7.org/linux/man-pages/man3/io_uring_register_buf_ring.3.html

As mentioned in the readme, this code has only been tested with kernel version 6.0.9.

I hope that helps!
