This change is really a non-starter unless the information gets
published somewhere where people actually look at dumped sockets, and
that's inet_diag and friends.

Would it make sense to also make UDIAG_SHOW_NAME use sk_description?
(And keep the existing change - setsockopt + show_fd_info via
/proc/.../fdinfo/..)

I would feel like adding a pid information (and what else am I missing
here) to inet_diag might also be a good improvement then?

I understand that users have to scan /proc to find the FDs, matching
the inode number for the socket to find the owning process today.

If that's of interest I can explore that too
