So in this version I splited the patches to make them clear I removed the DECLARE_PNET since it was apparently using too many capital letters :) Thanks [PATCH] nets: Introduce read_pnet() and write_pnet() helpers This patch introduces two helpers that deal with reading and writing struct net pointers in various network structures. Their implementation depends on CONFIG_NET_NS For symmetry, both functions work with "struct net **pnet". Their usage should reduce the number of #ifdef CONFIG_NET_NS, without adding many helpers for each network structure that hold a "struct net *pointer" Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> --- include/net/net_namespace.h | 18 ++++++++++++++++++ 1 files changed, 18 insertions(+)
