Re: [PATCH v2 2/2] net: socket: implement SO_DESCRIPTION

This command attaches the zero terminated string in optval to the
socket for troubleshooting purposes. The free string is displayed in the
process fdinfo file for that fd (/proc/<pid>/fdinfo/<fd>).

One intended usage is to allow processes to self-document sockets
for netstat and friends to report

We ignore optlen and constrain the string to a static max size

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.
