From c58dc01babfd58ec9e71a6ce080150dc27755d88 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 27 Apr 2010 15:05:31 -0700 Subject: net: Make RFS socket operations not be inet specific. Idea from Eric Dumazet. As for placement inside of struct sock, I tried to choose a place that otherwise has a 32-bit hole on 64-bit systems. Signed-off-by: David S.
