Message-Id: <1237412967-20754-1-git-send-email-dmitri.vorobiev@movial.com> Date: Wed, 18 Mar 2009 23:49:25 +0200 From: Dmitri Vorobiev <dmitri.vorobiev@...ial.com> To: akpm@...ux-foundation.org, linux-kernel@...r.kernel.org Cc: Dmitri Vorobiev <dmitri.vorobiev@...ial.com> Subject: [PATCH 1/3] Restrict definition of a variable in kernel/sysctl.c The variable "one" in kernel/sysctl.c is used only if either CONFIG_HIGHMEM, or CONFIG_DETECT_SOFTLOCKUP are defined (or both). Hence, if neither option is enabled, the following error is produced: CC kernel/sysctl.o kernel/sysctl.c:99: warning: 'one' defined but not used This patch fixes the warning by moving the variable definition under an appropriate preprocessor construct.
