Subject[PATCH 00/32 v3] perf/core improvements and fixes
From: Arnaldo Carvalho de Melo <>

Hi Ingo,

Ingo, this is the 3rd try, this time removing the last two patches in
the series, from Jean, till we get the problems I found and the one reported by
Jiri sorted out.

Jiri told me the problem exhibits when one doesn't have libunwind devel
files installed.

At some point we're considering using things like the 'mock' tool to
do the tools/perf/tests/ builds tests with all possible development packages
combos to detect these kinds of problems earlier.

Please consider applying,

Best Regards,

- Arnaldo
