From 7344e29f285a94b965075599731811c352f3ab40 Mon Sep 17 00:00:00 2001 From: Song Liu Date: Mon, 23 Oct 2017 09:20:23 -0700 Subject: tcp: mark trace event arguments sk and skb as const Some functions that we plan to add trace points require const sk and/or skb. So we mark these fields as const in the tracepoint. Signed-off-by: Song Liu Signed-off-by: David S.
