[PATCH 4.4-cip 02/23] ubsan: cosmetic fix to Kconfig text


Ben Hutchings <ben.hutchings@...>
 

From: Yang Shi <yang.shi@linaro.org>

commit 7707535ab95e2231b6d7f2bfb4f27558e83c4dc2 upstream.

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.
