Subject: Re: [PATCH v5 4/4] net: diag: Support destroying TCP socketsr

Thanks for the reviews. This version fixes a few issues and
addresses Tom's comments on v5. Specifically:

1. As requested by Tom, tcp_abort is no longer behind a config
   option, and now allows the caller to specify the error with
   which to interrupt blocking operations. (The SOCK_DIAG
   codepath to close TCP sockets from userspace always uses
   ECONNABORTED.)

2. Config symbols are checked with "ifdef" not "if".

3. The boolean Kconfig option no longer depends on
   INET_DIAG && (IPV6 || IPV6=n) but only on INET_DIAG

The name of the operation is still SOCK_DESTROY, and the
functions that implement it still have "destroy" in their
name. I'm leaning towards changing this to SOCK_ABORT instead,
both to reduce confusion with e.g., sock_diag_destroy_group,
and because it seems more correct in general, at least for
TCP. Thoughts on the name?
