From 57ee24144e57b762dc46f171e1f138ccfc464867 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 21 Jun 2017 21:16:59 +0200 Subject: [PATCH] ARM: exynos_defconfig: Enable locking test options exynos_defconfig, beside serving as a reference config for Exynos-based devices, is used by developers during regular development work. Enabling options responsible for locking tests allows to discover bugs in drivers and mach code earlier. This enables: 1. Detection of sleeping in atomic sections (DEBUG_ATOMIC_SLEEP), 2. Full lockdep (DEBUG_LOCK_ALLOC and PROVE_LOCKING which makes other lock debug entries unneeded), 3. Detection of soft, kernel lockups (SOFTLOCKUP_DETECTOR).
