[PATCHSET 0/7] perf tools: Check error during collapsing hist entries

[Namhyung Kim]

Hi,

This patchset checks error case during the process of collapsing hist
entries.  It's a preparation of upcoming hierarchy patchset which adds
more work in the collapsing path.  If there's an error during this
stage, it'll stop processing and show warning to user.

Thanks,
Namhyung
