There are two reasons to use outline instrumentation: 1. Outline instrumentation reduces the size of the kernel text, and should be used where this size matters. 2. Outline instrumentation is less invasive and can be used for debugging for KASAN developers, when it's not clear whether some issue is caused by KASAN or by something else. For the rest cases inline instrumentation is preferrable, since it's faster. This patch changes the default instrumentation mode to inline. --- lib/Kconfig.kasan | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/Kconfig.kasan b/lib/Kconfig.kasan index ab34e7d7d3a7..8ea6ae26b4a3 100644 --- a/lib/Kconfig.kasan +++ b/lib/Kconfig.kasan @@ -70,7 +70,7 @@ config KASAN_EXTRA choice prompt "Instrumentation type" depends on KASAN - default KASAN_OUTLINE + default KASAN_INLINE config KASAN_OUTLINE bool "Outline instrumentation" -- 2.16.2.395.g2e18187dfd-goog -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
