From de1d7286060430e79a1d50ad6e5fee8fe863c5f6 Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Tue, 5 May 2009 16:49:59 +0800 Subject: tracepoint: trace_sched_migrate_task(): remove parameter The orig_cpu parameter in trace_sched_migrate_task() is not necessary, it can be got by using task_cpu(p) in the probe.
