Subject: [RFC PATCH bpf-next 02/13] proc_ns: Extend the field type in struct proc_ns_operations to long

In struct proc_ns_operations, the field 'type' is the new namespace
clone flag. As the newly introduced CLONE_NEWBPF is more than 32bit,
we need also extend this field from int to long to adapt to this change.
