From 7b8b59617ead5acc6ff041a9ad2ea1fe7a58094f Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 20 Oct 2011 09:22:18 +0000 Subject: [PATCH] igbvf: fix truesize underestimation igbvf allocates half a page per skb fragment. We must account PAGE_SIZE/2 increments on skb->truesize, not the actual frag length. Signed-off-by: Eric Dumazet CC: Jeff Kirsher Signed-off-by: David S.
