#include <linux/io_uring.h>
^~~~~~~~~~~~~~~~~~
Kernel version 5.4.0-80.
I have not found a way to install the API header files. The ABI should be supported though.
On Ubuntu (which I’m guessing is what you’re using, based on the kernel version), you’ll find linux/io_uring.h in linux-libc-dev. Install that:
sudo apt install linux-libc-dev
and you should find the header in /usr/include/linux.
Programs written using liburing use that library’s headers, so installing that is unlikely to help; but if you want to try, the relevant package is liburing-dev. The io_uring.h header there defines the same interface as the kernel UAPI’s io_uring.h.
A development package for liburing likely needs installing, e.g. on CentOS it's luburing-develop. See example at https://centos.pkgs.org/8/centos-powertools-x86_64/liburing-devel-1.0.7-3.el8.x86_64.rpm.html
Also note that the include of <linux/io_uring.h> might need revising to be <liburing/io_uring.h> due to where the package has placed the file.
