* Before 2.6.20, kmem_cache_t was the accepted way to refer to a kmem_cache
31
* structure. Prior to 2.6.15, this structure was called kmem_cache_s, and
32
* afterwards it was renamed to kmem_cache. Here we keep things simple and use
33
* the accepted typedef until it became deprecated, at which point we switch
34
* over to the kmem_cache name.

46
