This patch series adds meta-data support to perf record/report in pipe
perf record -o - foo | perf inject -b | perf report -i -

We had meta-data (information about host configuration, perf tool version,...)
in regular (file) mode but it was lacking in pipe mode. This patch series fixes

In addition to this change, I think it'd be great if we keep this
meta-data somewhere for later use - I guess perf report and
annotate on TUI, at least, will need it too. Just a suggestion :).


It is there -- see perf-report header. It gets dropped on pipe mode b/c the meta-data is in the header.
