[PATCH 00/18] perf report: Add support for event group view (v6)

[Namhyung Kim]

Hi all,

This is my 6th iteration of event group view patchset.
For basic idea and usage example, please see my original post [1].

The largest change in this version is using 'pairs' list of hist_entry
instead of allocating group_stats for all group members.  But I needed
to allocate temporary arrays for internal purpose anyway.  If you have
a better solution please let me know.

Jiri, sorry for the delay.  I had to hunt down some nasty bugs in my
patches.  And I saw you submitted the multiplu diff series which will
conflict my changes.  I'll have a look at it soon, and I'd be glad if
you take a look at my changes too. :)

You can get this series via my tree at:

Any comments are welcome, thanks,
Namhyung
