From 71a84b5aedf5023f4009c3bbf28ecba256201f87 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 24 Apr 2018 11:58:56 -0300 Subject: perf thread: Make thread__find_map() return the map It was returning the searched map just on the addr_location passed, with the function itself returning void. Make it return the map so that we can make the code more compact.
