From 6e54abac1b8e0b7febffdbad37b605daef1cfcff Mon Sep 17 00:00:00 2001 From: Andrey Ryabinin Date: Thu, 16 Apr 2015 12:44:58 -0700 Subject: kasan: Makefile: shut up warnings if CONFIG_COMPILE_TEST=y It might be annoying to constantly see this: scripts/Makefile.kasan:16: Cannot use CONFIG_KASAN: -fsanitize=kernel-address is not supported by compiler while performing allmodconfig/allyesconfig build tests. Disable this warning if CONFIG_COMPILE_TEST=y.
