ftrace: CPU buffer start annotation clean ups ...
Impact: better handling of CPU buffer start annotation
Because of the confusion with the per CPU buffers wrapping where
one CPU might be more active at the end of the trace than the other
CPUs causing that one CPU to have a shorter history. Kernel
developers were confused by the "missing" data of that one CPU
at the beginning of the trace output. An annotation was added to
the trace output to show that the buffer had started:
# tracer: function
#
# TASK-PID CPU# TIMESTAMP FUNCTION
# | | | | |
##### CPU 3 buffer started ####
<idle>-0 [003] 158.192959: smp_apic_timer_interrupt
[...]
<idle>-0 [003] 161.556520: default_idle
##### CPU 1 buffer started ####
<idle>-0 [001] 161.592494: hrtimer_force_reprogram
[etc]
But this annotation gets a bit messy when tracers do not fill the
buffers. This patch does a couple of things:
One) it adds a flag to trace_options to disable these annotations
Two) it does not annotate if the tracer did not overflow its buffer.
This makes the output much cleaner.
