Modified Files: src/sys/kern: files.kern subr_kmem.c Log Message: Retire KMEM_REDZONE and KMEM_POISON. KMEM_REDZONE is not very efficient and cannot detect read overflows. KASAN can, and will be used instead. KMEM_POISON is enabled along with KMEM_GUARD, but it is redundant, since the latter can detect read UAFs contrary to the former. In fact maybe KMEM_GUARD should be retired too, because there are many cases where it doesn't apply. Simplifies the code.
