kmem_cache_destroy — delete a cache
void kmem_cache_destroy ( | struct kmem_cache * | cachep); |
Remove a struct kmem_cache object from the slab cache.
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.
