The library should not use a static copy, as that creates problems on how to conform to what the kernel expects. One example is the struct sctp_event_subscribe, which the kernel only accepts buffers up to the size it wants. Larger buffers, which would happen if an updated library is built/ran under an old kernel, are rejected. Subsequent patches will adjust the library so it can adapt itself to the kernel-headers available at compile time.
