From f3438bc7813c439a06104ba074301c8bdd64ac8b Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 4 Jul 2016 09:50:23 +0000 Subject: [PATCH] timers, net/ipv4/inet: Initialize connection request timers as pinned Pinned timers must carry the pinned attribute in the timer structure itself, so convert the code to the new API. No functional change.
