bdevperf application is utilized in multiple test scenarios and most prominently in SPDK performance reports. Similar to perf and fio_plugins, it is used to measure performance. It is intended to represent the expected behavior of users application that use SPDK bdev layer. Applications under --enable-tests are intended for specific test scenarios and user interaction is usually via a test scripts. Meanwhile --enable-examples are used more broadly to teach and show usage of SPDK libraries. As an added benefit with this patch, its possible to compile bdevperf without need to satisfy additional requirements to compile all the test applications.
