From f54020eb8155371725ab75b0fc5c419287eca084 Mon Sep 17 00:00:00 2001 From: Giacomo Travaglini Date: Mon, 4 Jun 2018 09:40:19 +0100 Subject: misc: Using smart pointers for memory Requests This patch is changing the underlying type for RequestPtr from Request* to shared_ptr. Having memory requests being managed by smart pointers will simplify the code; it will also prevent memory leakage and dangling pointers.
