Frederic Weisbecker 3786310afe perf sched: Add max delay time snapshot 
When we have a maximum latency reported for a task, we need a
convenient way to find the matching location to the raw traces
or to perf sched map that shows where the task has been
eventually scheduled in. This gives a pointer to retrieve the
events that occured during this max latency.

Julia Lawall 5660ce3424 perf tools: Correct size given to memset 
Memset should be given the size of the structure, not the size

Xiao Guangrong c0c9e72150 perf sched: Fix for getting task's execution time 
In current code, task's execute time is got by reading
'/proc/<pid>/sched' file, it's wrong if the task is created
by pthread_create(), because every thread task has same pid.

This way also has two demerits:

 1: 'perf sched replay' can't work if the kernel is not
    compiled with the 'CONFIG_SCHED_DEBUG' option

 2: perf tool should depend on proc file system

So, this patch uses PERF_COUNT_SW_TASK_CLOCK to get task's
execution time instead of reading /proc file.

Changelog v2 -> v3:
use PERF_COUNT_SW_TASK_CLOCK instead of rusage() as Ingo's
suggestion

Masami Hiramatsu d1bde3f755 perf probe: Fix add-probe command syntax without --add option 
Fix add-probe command syntax without --add option.
perf-probe supports add-probe command without --add
option. But it treats each argument as an event definition.
e.g.

perf probe func arg1 arg2

 is interpreted as

perf probe --add func --add arg1 --add arg2

But it may be useless in many cases.

This patch fixes this syntax to fold those arguments into
one event definition if there is no --add option. With this
change, above command is interpreted as below;

perf probe --add "func arg1 arg2"

Ulrich Drepper 180570fdb7 perf tools: Optimize parse_subsystem_tracepoint_event() 
Uses of strcat are almost always signs that someone is too lazy
to think about the code a bit more carefully.  One always has to
know about the lengths of the strings involved to avoid buffer
overflows.

This is one case where the size of the object code for me is
reduced by 38 bytes.  The code should also be faster, especially
if flags is non-NULL.

OGAWA Hirofumi 7691b1ec2e perf tools: Misc small fixes 
- util/header.c
	"len" is aligned to 64. So, it tries to write the out of
	long_name buffer.

	So, this use "zero_buf" to write aligned area.

- util/trace-event-read.c
	"size" is not including nul byte. So, this allocates it, and set '\0'.

- util/trace-event-parse.c
	It needs parens to calc correct size.
