NAME

       kmem_cache_destroy - delete a cache

SYNOPSIS

       int kmem_cache_destroy  (kmem_cache_t * cachep);

ARGUMENTS

       cachep the cache to destroy

DESCRIPTION

       Remove a kmem_cache_t object from the slab cache. Returns 0 on success.

       It is expected this function will be called by  a  module  when  it  is
       unloaded.  This will remove the cache completely, and avoid a duplicate
       cache being allocated each time a module is loaded and unloaded, if the
       module  doesn’t  have  persistent  in-kernel  storage  across loads and
       unloads.

       The cache must be empty before calling this function.

       The caller must guarantee that noone  will  allocate  memory  from  the
       cache during the kmem_cache_destroy.
