    slab: Generify kernel pointer validation · fc1c1833
    Pekka Enberg authored
    As suggested by Linus, introduce a kern_ptr_validate() helper that does some
    sanity checks to make sure a pointer is a valid kernel pointer.  This is a
    preparational step for fixing SLUB kmem_ptr_validate().
