User of this controller will use get_curernt_misc_cg() API which returns a pointer. Ideally the user should use this pointer and they shouldn't have any need to access "css" in their code. They also don't need to create a object of 'struct misc_cg{}', because that won't be correct misc cgroup object. They should just declare a pointer like we are doing here in 'struct kvm_sev_info {}'. If they do need to use "css" then they can include cgroup header in their code. Let me know if I am overlooking something here. Thanks Vipin Sharma
