[PATCH v2 0/2] tests/qtest: Only run fuzz-tests when tested devices are available

[PATCH v2 0/2] tests/qtest: Only run fuzz-tests when tested devices are available

[Philippe Mathieu-Daudé]

Some tests/qtest/fuzz-test fail when the device tested is
not available in the build. Fix this by only running the
test when devices are available.

FWIW Alexander Bulekov suggested an improvement, putting each
test in a directory named by the device tested. This series
does not cover that.

[PATCH v2 1/2] tests/qtest: Only run fuzz-megasas-test if megasas device is available

[Philippe Mathieu-Daudé]

This test fails when QEMU is built without the megasas device,
restrict it to its availability.

I assume Alexander will take this patch through his fuzzer branch now? Or 
shall I take it via the qtest branch?

Forgot, since v1:

- Do not make the testing generic, keep it restricted to x86 (thuth)

[PATCH v2 3/2] MAINTAINERS: Cover fuzzer reproducer tests within 'Device Fuzzing'

[Philippe Mathieu-Daudé]

When we started to commit the fuzzer QTest reproducers to
fuzz-test.c in commit d8dd1095019 ("qtest: add fuzz test case"),
we forgot to add the corresponding MAINTAINERS entry. Do it now.
