From 73215849dfbf63421c1cafea5a1b6da9bb17831e Mon Sep 17 00:00:00 2001 From: Byungchul Park Date: Fri, 12 May 2017 09:39:44 +0900 Subject: [PATCH] sched/core: Use the new llist_for_each_entry_safe() primitive Now that we've added llist_for_each_entry_safe(), use it to simplify an open coded version of it in sched_ttwu_pending().
