Subject: C12 [02/19] slub: Use kmem_cache for the kmem_cache structure
Date: Mon, 20 Aug 2012 20:50:35 +0000	[thread overview]
Message-ID: <0000013945cd23c0-fb48fffb-7f4d-4ade-9ad7-9f30d2cbf62c-000000@email.amazonses.com> (raw)
In-Reply-To: <20120820204021.494276880@linux.com>

Do not use kmalloc() but kmem_cache_alloc() for the allocation
of the kmem_cache structures in slub.
