Subject: C12 [07/19] Move freeing of kmem_cache structure to common code
Date: Mon, 20 Aug 2012 20:50:37 +0000 [thread overview]
Message-ID: <0000013945cd2be9-84e87bad-2bdc-475e-b591-dc77565e71db-000000@email.amazonses.com> (raw)
In-Reply-To: <20120820204021.494276880@linux.com>
The freeing action is basically the same in all slab allocators.
Move to the common kmem_cache_destroy() function.
