This ended up not being included in the mainline version of io_uring, so drop it from the test app as well. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

This directory includes a few programs that demonstrate how to use io_uring in an application. The examples are: io_uring-cp A very basic io_uring implementation of cp(1). It takes two arguments, copies the first argument to the second. This example is part of liburing, and hence uses the simplified liburing API for setting up an io_uring instance, submitting IO, completing IO, etc. The support functions in queue.c and setup.c are straight out of liburing. io_uring-bench Benchmark program that does random reads on a number of files. This app demonstrates the various features of io_uring, like fixed files, fixed buffers, and polled IO. There are options in the program to control which features to use. Arguments is the file (or files) that io_uring-bench should operate on. This uses the raw io_uring interface. liburing can be cloned with git here: git://git.kernel.dk/liburing and contains a number of unit tests as well for testing io_uring. It also comes with man pages for the three system calls. Fio includes an io_uring engine, you can clone fio here: git://git.kernel.dk/fio
