nit: should you do #include <linux/cgroup.h>?
Otherwise, css may be undefined.

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.
