Hi everyone, In preparation for ConfigFS support, a flexible way to configure VKMS device(s) is required. This series adds the required APIs to create a configuration, the code changes required to apply it and KUnit test validating the changes.
Louis Chauvet and I are working on ConfigFS support. In this series I tried to merge his changes [1] with mine [2]. I kept his Signed-off-by to reflect that, even if I show up as the author of some/most of the patches, this was a joint effort. I'm still polishing the ConfigFS code [3] and its IGT tests [4] (connector hot-add/remove bugs) but the IGT tests also exercise this series and can be used for additional test coverage.
