Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.

I suggest to replace the word “new” by a reference to the commit 8eb8284b412906181357c2b0110d879d5af95e52
("usercopy: Prepare for usercopy whitelisting").

See also related background information from 2017-06-10.

Regards,
Markus
