Message-ID: <4EDE575B.3010507@parallels.com>

Subject: [PATCH 1/11] inet_diag: Partly rename inet_ to sock_
The ultimate goal is to get the sock_diag module, that works in
family+protocol terms. Currently this is suitable to do on the
inet_diag basis, so rename parts of the code. It will be moved
to sock_diag.c later.
