Message-Id: <1455300862-453-1-git-send-email-yang.shi@linaro.org> Date: Fri, 12 Feb 2016 10:14:22 -0800 From: Yang Shi <yang.shi@...aro.org> To: mingo@...hat.com, peterz@...radead.org Cc: linux-kernel@...r.kernel.org, linaro-kernel@...ts.linaro.org, yang.shi@...aro.org Subject: [PATCH] lib/Kconfig: make PREEMPT_COUNT depend on PREEMPT in DEBUG_ATOMIC_SLEEP When building non-preempt kernel (PREEMPT_NONE), PREEMPT_COUNT is still enabled if DEBUG_ATOMIC_SLEEP is enabled. But, it sounds not make sense to have PREEMPT_COUNT set in non-preempt kernel. So, make PREEMPT_COUNT depend on PREEMPT here.
