From c2636b4d9e8ab8d16b9e2bf0f0744bb8418d4026 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 23 Oct 2007 21:07:32 -0700 Subject: [NET]: Treat the sign of the result of skb_headroom() consistently In some places, the result of skb_headroom() is compared to an unsigned integer, and in others, the result is compared to a signed integer.
