Perhaps I can add an option that will prevent the snapshots as well. Perhaps an option called "quiet", and a "no_snapshot" one too. I can create the no snapshot one. But this should be converted to "quiet" and added as a tracer specific option. -- Steve > Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> > CC: Thomas Gleixner <tglx@linutronix.de> > CC: Steven Rostedt <rostedt@goodmis.org> > CC: Ingo Molnar <mingo@redhat.com> > CC: Peter Zijlstra <peterz@infradead.org> > --- > kernel/trace/trace.c | 4 +++- > kernel/trace/trace.h | 1 + > kernel/trace/trace_irqsoff.c | 19 +++++++++++-------- > 3 files changed, 15 insertions(+), 9 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
