From 46b93b74fc022885ab69dfc8e2af0562dd626638 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 31 Aug 2010 16:35:20 -0400 Subject: [PATCH] tracing/lockdep: Fix dependency of TRACE_IRQFLAGS When CONFIG_IRQSOFF_TRACER is set and CONFIG_PROVE_LOCKING is not, we get the following error: $ make oldconfig scripts/kconfig/conf --oldconfig arch/x86/Kconfig warning: (IRQSOFF_TRACER && TRACING_SUPPORT && FTRACE && TRACE_IRQFLAGS_SUPPORT && !ARCH_USES_GETTIMEOFFSET) selects TRACE_IRQFLAGS which has unmet direct dependencies (DEBUG_KERNEL && TRACE_IRQFLAGS_SUPPORT && PROVE_LOCKING) warning: (IRQSOFF_TRACER && TRACING_SUPPORT && FTRACE && TRACE_IRQFLAGS_SUPPORT && !ARCH_USES_GETTIMEOFFSET) selects TRACE_IRQFLAGS which has unmet direct dependencies (DEBUG_KERNEL && TRACE_IRQFLAGS_SUPPORT && PROVE_LOCKING) This is because IRQSOFF_TRACER selects TRACE_IRQFLAGS but TRACE_IRQFLAGS has PROVE_LOCKING as a dependency. This code is incorrect, and this patch changes the TRACE_IRQFLAGS to be just a simple bool that does not depend or select anything. Instead both IRQSOFF_TRACER and PROVE_LOCKING select it.
