io_uring: kill io_uring userspace examples

2023-08-09T16:46:46Z

There are tons of io_uring tests and examples in liburing and on the Internet. If you're looking for a benchmark, io_uring-bench.c is just an acutely outdated version of fio/io_uring. And for basic condensed init template for likes of selftests take a peek at io_uring_zerocopy_tx.c. Kill tools/io_uring/, it's a burden keeping it here.

tools/io_uring: sync with liburing

2019-05-23T16:25:26Z

Various fixes and changes have been applied to liburing since we copied some select bits to the kernel testing/examples part, sync up with liburing to get those changes. Most notable is the change that split the CQE reading into the peek and seen event, instead of being just a single function. Also fixes an unsigned wrap issue in io_uring_submit(), leak of 'fd' in setup if we fail, and various other little issues. Signed-off-by: Jens Axboe

io_uring: add a few test tools

2019-03-06T20:00:16Z

This adds two test programs in tools/io_uring/ that demonstrate both the raw io_uring API (and all features) through a small benchmark app, io_uring-bench, and the liburing exposed API in a simplified cp(1) implementation through io_uring-cp. Signed-off-by: Jens Axboe
