Date: Fri, 5 Feb 2016 16:05:13 -0800 From: Yang Shi <yang.shi@...aro.org> To: aryabinin@...tuozzo.com Cc: linux-kernel@...r.kernel.org, linaro-kernel@...ts.linaro.org, yang.shi@...aro.org Subject: [PATCH] ubsan: cosmetic fix to Kconfig text When enabling UBSAN_SANITIZE_ALL, the kernel image size gets increased significantly (~3x). So, it sounds better to have some note in Kconfig. And, fixed a typo.
