- * kmem_cache_create_usercopy - Create a cache with a region suitable

- * @size: The size of objects to be created in this cache.
- * @align: The required alignment for the objects.
- * @flags: SLAB flags
- * @useroffset: Usercopy region offset

- * Cannot be called within a interrupt, but can be interrupted.

- * %SLAB_POISON - Poison the slab with a known test pattern (a5a5a5a5)
- * to catch references to uninitialised memory.
- *
- * %SLAB_RED_ZONE - Insert `Red` zones around the allocated memory to check
- * for buffer overruns.

- * %SLAB_HWCACHE_ALIGN - Align the objects in this cache to a hardware

- * as davem.
- *
- * Return: a pointer to the cache on success, NULL on failure.
