From 0ac1dd5b4a70cfc8591dd9426f800b484765badb Mon Sep 17 00:00:00 2001 From: Kyle Meyer Date: Tue, 27 Aug 2019 16:43:46 -0500 Subject: [PATCH] perf timechart: Refactor svg_build_topology_map() Exchange the parameters of svg_build_topology_map() with 'struct perf_env *env' and adjust the function accordingly. This patch should not change any behavior, it is merely refactoring for the following patch. Committer notes: No need to include env.h from svghelper.h, all it needs is a forward declaration for 'struct perf_env', so move the include directive to svghelper.c, where it is really needed.
