This patch series adds support for thread stack and callchain; this patch set depends on the instruction sample fix patch set [1].
This patch set get more complex, so before divide into small groups, I'd like to use this patch set version to include all relevant patches, hope this can give whole context for related code change.
Was this split up into small groups and sent again? I didn't see anything when searching lkml.
