When the execution of live migration fails, the user can view the status and data during the migration process separately from the source and the destination, which is convenient for users to analyze and locate problems. Changes v2 -> v3 Extend the debugfs function from hisilicon device to vfio. Changes v1 -> v2 Change the registration method of root_debugfs to register with module initialization.
