Subject: [PATCH 1/4] perf tools: Rename group to topdown
From: Kan Liang <kan.liang@...ux.intel.com>
The group.h/c only include TopDown group related functions. The name
"group" is too generic and inaccurate. Use the name "topdown" to
replace it.
Move topdown related functions to a dedicated file, topdown.c.
Signed-off-by: Kan Liang <kan.liang@...ux.intel.com>
