Uday Shankar	a3835a4410	selftests: ublk: fix behavior when fio is not installed ... Some ublk selftests have strange behavior when fio is not installed. While most tests behave correctly (run if they don't need fio, or skip if they need fio), the following tests have different behavior: - test_null_01, test_null_02, test_generic_01, test_generic_02, and test_generic_12 try to run fio without checking if it exists first, and fail on any failure of the fio command (including "fio command not found"). So these tests fail when they should skip. - test_stress_05 runs fio without checking if it exists first, but doesn't fail on fio command failure. This test passes, but that pass is misleading as the test doesn't do anything useful without fio installed. So this test passes when it should skip. Fix these issues by adding _have_program fio checks to the top of all of these tests.

Ming Lei	8cb9b971e2	selftests: ublk: enable zero copy for null target ... Enable zero copy for null target so that we can evaluate performance from zero copy or not. Also this should be the simplest ublk zero copy implementation, which can be served as zc example. Add test for covering 'add -t null -z'.
