Yes, I also referred to LSM stacking and wondering if we need a module parameter to indicate which backends are registered at present. It would be nice for users to know which pstore backends are registered and selftest could take it for test easily. But I am worried about it would be confusing for users that there is a parameter pstore.backend to indicate which backends are allowed to be registered and another parameter to indicate which backends are registered now. At first the naming is a question.

Pstore now supports multiple backends, the module parameter pstore.backend varies from 'registered backend' to 'backends that are allowed to register'. Adjust selftests to match the change.
