From: Lv Zheng Date: Wed, 26 Apr 2017 08:18:33 +0000 (+0800) Subject: ACPICA: Debugger: Add interpreter blocking mark for single-step mode X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=069f9bf454a61d6fafa415dc2a8713938196d650;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ACPICA: Debugger: Add interpreter blocking mark for single-step mode ACPICA commit 91af5d18cd40b35f9d5568fb95fc403ff12474e5 When the single-step mode is used, evaluation is actually split by the single-step command prompts, so this patch correctly marks the evaluation segment with interpreter lock release/acquire. This in return fixes an issue that in the single-step command prompt, commands requiring to hold the namespace lock (ex. namespace) cannot be executed. ACPICA BZ 1362, fixed by Lv Zheng.
