From 1c213bd24ad04f4430031d20d740d7783162b099 Mon Sep 17 00:00:00 2001 From: WANG Cong Date: Thu, 13 Feb 2014 11:46:28 -0800 Subject: net: introduce netdev_alloc_pcpu_stats() for drivers There are many drivers calling alloc_percpu() to allocate pcpu stats and then initializing ->syncp. So just introduce a helper function for them. Cc: David S. Miller Signed-off-by: Cong Wang Signed-off-by: David S.
