virt: vbox: Remove unproper information

2022-09-09T08:19:18Z

When drivers are working properly, they are quiet. Therefore, the vbg_info() should be removed. Suggested-by: Greg Kroah-Hartman Reviewed-by: Hans de Goede Signed-off-by: Jiasheng Jiang Link: https://lore.kernel.org/r/20220901144619.3550352-1-jiasheng@iscas.ac.cn Signed-off-by: Greg Kroah-Hartman

virt: vbox: convert to use dev_groups

2022-09-09T08:19:04Z

The driver core supports the ability to handle the creation and removal of device-specific sysfs files in a race-free manner. Moreover, it can guarantee the success of creation. Therefore, it should be better to convert to use dev_groups.

kunit: fix Kconfig for build-in tests USB4 and Nitro Enclaves

2022-09-01T19:00:48Z

Both the USB4 and Nitro Enclaves KUNIT tests are now able to be compiled if KUNIT is compiled as a module. This leads to issues if KUNIT is being packaged separately from the core kernel and when KUNIT is run baremetal without the required driver compiled into the kernel.

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

nitro_enclaves: test: Use kunit_test_suite() macro

2022-07-11T23:13:27Z

The kunit_test_suite() macro previously conflicted with module_init, making it unsuitable for use in the nitro_enclaves test. Now that it's fixed, we can use it instead of a custom call into internal KUnit functions to run the test. As a side-effect, this means that the test results are properly included with other suites when built-in. To celebrate, enable the test by default when KUNIT_ALL_TESTS is set (and NITRO_ENCLAVES enabled). The nitro_enclave tests can now be run via kunit_tool with: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_SMP=y \ --kconfig_add CONFIG_HOTPLUG_CPU=y \ --kconfig_add CONFIG_VIRT_DRIVERS=y \ --kconfig_add CONFIG_NITRO_ENCLAVES=y \ 'ne_misc_dev_test' (This is a pretty long command, so it may be worth adding a .kunitconfig file at some point, instead.)
