From: David Howells Date: Thu, 8 Sep 2016 10:10:12 +0000 (+0100) Subject: rxrpc: Remove skb_count from struct rxrpc_call X-Git-Tag: v4.9-rc1~127^2~247^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2ab27215ea27475a0b279732ba8a934bfab57ef0;p=platform%2Fkernel%2Flinux-exynos.git rxrpc: Remove skb_count from struct rxrpc_call Remove the sk_buff count from the rxrpc_call struct as it's less useful once we stop queueing sk_buffs.
