Message-Id: <1441913708-15532-2-git-send-email-matthias.tafelmeier@gmx.net>
Date: Thu, 10 Sep 2015 21:34:59 +0200

Subject: [PATCH v7 01/10] ss: rooted out ss type declarations for output formatters
The prospected output formatters and ss do share type declarations like
slabstat or tcpstat so that the decision has been made to centralize
those declarations in ss_types.h. Potential future declarations shall
be placed there. The latter should help amend the extent of ss.c as
well.
