From 80a9201a5965f4715d5c09790862e0df84ce0614 Mon Sep 17 00:00:00 2001 From: Alexander Potapenko Date: Thu, 28 Jul 2016 15:49:07 -0700 Subject: mm, kasan: switch SLUB to stackdepot, enable memory quarantine for SLUB For KASAN builds: - switch SLUB allocator to using stackdepot instead of storing the allocation/deallocation stacks in the objects; - change the freelist hook so that parts of the freelist can be put into the quarantine.
