[PATCH 05/11] perf hists: Collapse expanded callchains after filter is applied

From: Namhyung Kim
Date: Thu Apr 24 2014 - 04:26:42 EST


When a filter is applied a hist entry checks whether its callchain was
folded and account it to the output stat. But this is rather hacky
and only TUI-specific. Simply fold the callchains for the entry looks
like a simpler and more generic solution IMHO.
