From 2b5d12b68514e3d81086a65fc8496822d5bd4359 Mon Sep 17 00:00:00 2001 From: Matheus Tavares Bernardino Date: Wed, 12 Jun 2024 14:04:46 -0300 Subject: [PATCH] cpu: fix memleak of 'halt_cond' and 'thread' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since a4c2735f35 (cpu: move Qemu[Thread|Cond] setup into common code, 2024-05-30) these fields are now allocated at cpu_common_initfn(). So let's make sure we also free them at cpu_common_finalize(). Furthermore, the code also frees these on round robin, but we missed 'halt_cond'.
