From 5b12adc849be011fd6d99a16e39d83afee43c0a0 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 11 Oct 2017 17:01:36 +0200 Subject: [PATCH] perf annotate: Move rb_node to struct annotation_line Move rb_node to struct annotation_line to make struct annotation_line the rb tree node for sorted lines used in both stdio and TUI code. This way we can unite the sorted lines lines codes for both TUI and stdio in the following patches.
