Subject: [PATCH RESEND] cred: Use KMEM_CACHE instead of kmem_cache_create

From: Kunwu Chan <chentao@...inos.cn>

commit 0a31bd5f2bbb ("KMEM_CACHE(): simplify slab cache creation")
introduces a new macro.
Use the new KMEM_CACHE() macro instead of direct kmem_cache_create
to simplify the creation of SLAB caches.

Notes:
    I'am Kunwu.Chan, the problem(https://lore.kernel.org/all/CAHC9VhTJXfPztz2W_V6sp41PJW8dzvZH0YdnRXd7tUZOF1Q09Q@mail.gmail.com/) may be caused by my email server.
    I change the email and send it to myself, the raw email seems ok.
    So i resend it.
