Netlink is absolutely atrocious to work with because everything is
variable sized and figuring out the correct allocation size is a
complete nightmare even with the "helpful" macros that are provided.

The bigger problem however is the complete untypedness even of the most
basic things. For example, retrieving the mtu of a network interface
through netlink is a complete nightmare. getdents, inotify, fanotify,
open_by_handle_at()'s struct fiel_handle are all fine. But let's
absolutely not take netlink as a model for anything related to mounts.

And no one is against again variable sized records per se. I think we're
coming to a good compromise here.
