From 17619322e56bce68290842889658ec5981f00a42 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Wed, 9 Aug 2023 13:22:52 +0100 Subject: io_uring: kill io_uring userspace examples 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 If you're looking for a benchmark, io_uring-bench.c is just an acutely outdated version of fio/io_uring.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.
