From e9cd8fa4fcfd67c95db9b87c0fff88fa23cb00e5 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 10 Mar 2016 12:54:16 +0100 Subject: [PATCH] sched/migration: Move calc_load_migrate() into CPU_DYING It really does not matter when we fold the load for the outgoing cpu. It's almost dead anyway, so there is no harm if we fail to fold the few microseconds which are required for going fully away.
