From efb3cb428dcde2356802b3f93e152efa7abc5a62 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 9 Dec 2011 06:22:26 +0000 Subject: [PATCH] inet_diag: Split inet_diag_get_exact into parts Similar to previous patch: the 1st part locks the inet handler and will get generalized and the 2nd one dumps icsk-s and will be used by TCP and DCCP handlers.
