From 29659ab4e7d02c08d8f2d08db0b0f708bd8b6771 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 7 Aug 2016 17:28:30 +0200 Subject: perf hists: Add support for header span Add span argument for header callback function. The handling of this argument is completely in the hands of the callback. The only thing the caller ensures is it's zeroed on the beginning. Omitting span skipping in hierarchy headers and gtk code. The c2c code use this to span header lines based on the entries span configuration.
