Re: [PATCH] tracing/function-graph-tracer: adjustments of thetrace informations

another thing which i'm sure you are aware of:
# tracer: function_graph
#
# TASK-PID CPU# TIMESTAMP FUNCTION
# | | | | |
------------------------------------------
| 1) S99local--1 => ssh-1724
------------------------------------------
1) 0.867 us | }
1) | mark_page_accessed() {
1) 0.293 us | constant_test_bit();
1) 0.294 us | constant_test_bit();
[...]
the header description is now out of of sync :-)
Also, we should probably not start the trace with a PID-switch event.
the last_pid[] markers are probably out of sync when we start printing
the trace.
So the output should probably be something like:
# tracer: function_graph
#
# CPU COST FUNCTION-GRAPH
# | | |
1) 0.867 us | }
1) | mark_page_accessed() {
1) 0.293 us | constant_test_bit();
1) 0.294 us | constant_test_bit();
[...]
