Hi Steven,
Would you review this patch for trace-cmd?
Thanks,

Hi Steven,
This patch series extracts the trace_clock file for switching outputting format
of timestamp. This patch series uses the options feature, so trace-cmd keeps
backward compatibility.
In tsc or counter modes, trace-cmd should output timestamp not in the sec.usec
format but in the raw format. For example, we will show results in trace-cmd
report mode as follows by applying this patch series:
<for local or global mode>
bash-9022 [000] 34984.109846: sched_wakeup:
comm=migration/3 pid=23 prio=0 success=1 target_cpu=003
<idle>-0 [002] 34984.109847: cpu_idle:
state=4294967295 cpu_id=2
bash-9022 [000] 34984.109848: sched_switch: prev_comm=bash
prev_pid=9022 prev_prio=120 prev_state=R ==> next_comm=migration/0 next_pid=8
next_prio=0
<idle>-0 [002] 34984.109849: sched_switch:
prev_comm=swapper/2 prev_pid=0 prev_prio=120 prev_state=R ==> next_comm=migration/2
next_pid=18 next_prio=0
<for tsc or counter mode>

comm=migration/3 pid=23 prio=0 success=1 target_cpu=003
<idle>-0 [002] 34984109847: cpu_idle:

prev_pid=9022 prev_prio=120 prev_state=R ==> next_comm=migration/0 next_pid=8
next_prio=0

v2:
- Separate input/output patches (2/3 and 3/3)
- Define TRACECMD_OPTION_TRACECLOCK for extracting trace_clock (2/3)
- Check whether TRACECMD_OPTION_TRACECLOCK exists or not in trace.dat (3/3)
v3:
- a file variable in save_tracing_file_data() is freed when operation is
failed
(1/3)
- check the return value of get_tracing_file() in save_tracing_file_data()
(1/3)
Thank you,
