From 470dda7417f284b9cfc96560b2acd98df63798a2 Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Thu, 26 Nov 2009 15:08:01 +0800 Subject: [PATCH] tracing: Restore original format of sched events The original format for sched_stat_iowait and sched_stat_sleep: $ cat events/sched/sched_stat_iowait/format ... print fmt: "comm=%s pid=%d delay=%Lu [ns]", ... $ cat events/sched/sched_stat_sleep/format ... print fmt: "comm=%s pid=%d delay=%Lu [ns]", ... But commit commit 75ec29ab848a7e92a41aaafaeb33d1afbc839be4 ("tracing: Convert some sched trace events to DEFINE_EVENT and _PRINT") broke the format: $ cat events/sched/sched_stat_iowait/format print fmt: "task: %s:%d iowait: %Lu [ns]", ... $ cat events/sched/sched_stat_sleep/format print fmt: "task: %s:%d sleep: %Lu [ns]", ... No change in functionality.
