Nit: the type of feature is u64 by define.
Yes, let me clarify once again,
type of features is u64, but in struct uffdio_api, which used for handling
UFFDIO_API.
Function userfault_msg is using in handle_userfault, when only
context (struct userfaultfd_ctx) is available, features inside context is
type of unsigned int and uffd_ctx_features is using for casting.
It's more likely question to maintainer, but due to userfaultfd_ctx is
internal only
structure, it's not a big problem to extend it in the future.
