The problem is that WE over netlink is basically using netlink to transfer the same binary blobs as the WE ioctls, rather than using properly structured netlink messages. > > One of the objections to having merged the API was that _if_ it were > > to gain users then we would have to carry that maintenance burden > > ad infinitum. > > More FUD.

The point is that if WE over netlink is used by applications, then the kernel must maintain that ABI (of WE over netlink) forever. - R.
