------------------------------------------------------ From: "Jason A. Donenfeld" Jason@zx2c4.com 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.
