Andrey Ryabinin 89d3c87e20 mm, slub, kasan: enable user tracking by default with KASAN=y ... It's recommended to have slub's user tracking enabled with CONFIG_KASAN, because: a) User tracking disables slab merging which improves detecting out-of-bounds accesses. b) User tracking metadata acts as redzone which also improves detecting out-of-bounds accesses. c) User tracking provides additional information about object. This information helps to understand bugs. Currently it is not enabled by default. Besides recompiling the kernel with KASAN and reinstalling it, user also have to change the boot cmdline, which is not very handy. Enable slub user tracking by default with KASAN=y, since there is no good reason to not do this.
