…y, need to check performance
… to cleanup tho. Performance is looking real good
…or modifying a struct rather than a pointer to a struct)
…bmitted to kernel, so updated to deal with that
…ead is maxed out at 426 Kp/s tho
… up compile errors
… free sqe function

liburingis the API library that wraps the underlyingio_uringLinux async I/O library. It provides an elegant interface to submit I/O tasks asynchronously to the kernel, vastly improving networking performance.Various linux distros ship with various linux kernels, each of which has a different version of
io_uringbaked in. Additionally, the package managers of different distro versions will ship different versions ofliburing. Adding on to the confusion, the developers ofliburing/io_uringhave changed, updated, and added features rapidly over the past couple years. This means a guide written 2 years ago may very well be out-of-date. A small example is how this otherwise great guide toliburingmentions how to use submission queue polling, you must register the file handlers before. This isn't true in recent versions.Takeaway here is I'll need to test what versions have the features our code uses and list these as
Supported Liburing/io_uring Versions
