From d8f9da240495b50766239410f9b0c715ca506a67 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 4 Jul 2019 12:06:20 -0300 Subject: perf tools: Use zfree() where applicable In places where the equivalent was already being done, i.e.: free(a); a = NULL; And in placs where struct members are being freed so that if we have some erroneous reference to its struct, then accesses to freed members will result in segfaults, which we can detect faster than use after free to areas that may still have something seemingly valid.
