From d403d0acc9c5afa679a3f61e71489530d7fa0606 Mon Sep 17 00:00:00 2001 From: Eric B Munson Date: Fri, 5 Mar 2010 12:51:06 -0300 Subject: perf session: Change add_hist_entry to take the tree root instead of session In order to minimize the impact of storing multiple events in a report this function will now take the root of the histogram tree so that the logic for selecting the proper tree can be inserted before the call.
