    mm/slab: document kfree() as allowed for kmem_cache_alloc() objects · ae65a521
    Vlastimil Babka authored
    This will make it easier to free objects in situations when they can
    come from either kmalloc() or kmem_cache_alloc(), and also allow
    kfree_rcu() for freeing objects from kmem_cache_alloc().
    
    For the SLAB and SLUB allocators this was always possible so with SLOB
    gone, we can document it as supported.
