[PATCH 0/4] perf report: Support custom output fields in hierarchy mode

[Namhyung Kim]

Hello,

This is to remove arbitrary restrictions in the hierarchy mode.

The -F/--fields option is to specify output fields and sort keys in perf
report exactly what users want.  It was not allowed in the hierarchy mode
because it missed to handle the field correctly.

This patchset addresses that problem and allows the option.  It'd make
the output more flexible.  For example, this is possible:

  $ perf report -F overhead,comm,dso -H

Thanks,
Namhyung
