From 1d28f42c1bd4bb2363d88df74d0128b4da135b4a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 12 Mar 2011 00:29:39 -0500 Subject: net: Put flowi_* prefix on AF independent members of struct flowi I intend to turn struct flowi into a union of AF specific flowi structs. There will be a common structure that each variant includes first, much like struct sock_common. This is the first step to move in that direction. Signed-off-by: David S.
