From dd275caf4a0d9b219fffe49288b6cc33cd564312 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 27 Jun 2018 23:26:20 -0700 Subject: kasan: depend on CONFIG_SLUB_DEBUG KASAN depends on having access to some of the accounting that SLUB_DEBUG does; without it, there are immediate crashes [1]. So, the natural thing to do is to make KASAN select SLUB_DEBUG.
