From: Eric Dumazet Date: Tue, 12 Jul 2011 03:08:34 +0000 (-0700) Subject: net: introduce __netdev_alloc_skb_ip_align X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4915a0de43c3e9aef92005c1f94a8ff3a6cfced5;p=linux-beck.git net: introduce __netdev_alloc_skb_ip_align RX rings should use GFP_KERNEL allocations if possible, add __netdev_alloc_skb_ip_align() helper to ease this.
