From 2dc9fb1a7bf013ce24dd34bc25283b60b966f015 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 14 Jan 2014 14:25:35 +0900 Subject: [PATCH] perf tools: Factor out sample__resolve_callchain() The report__resolve_callchain() can be shared with perf top code as it doesn't really depend on the perf report code. Factor it out as sample__resolve_callchain(). The same goes to the hist_entry__append_ callchain() too.
