NAMEkmem_cache_destroy − delete a cache

---

SYNOPSISvoid kmem_cache_destroy(struct kmem_cache * cachep);

---

ARGUMENTScachep the cache to destroy

---

DESCRIPTIONRemove 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​.
