From 60e7663d462af3994f292cb3691ea4f7371a9220 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 28 Mar 2008 16:39:10 -0700 Subject: [PATCH] [SOCK]: Drop per-proto inuse init and fre functions (v2). Constructive part of the set is finished here. We have to remove the pcounter, so start with its init and free functions. Signed-off-by: Pavel Emelyanov Acked-by: Eric Dumazet Signed-off-by: David S.
