[PATCH] selinux: replace kmem_cache_create() with KMEM_CACHE()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eric Suen <ericsu@xxxxxxxxxxxxxxxxxxx>

Based on guidance in include/linux/slab.h, replace kmem_cache_create()
with KMEM_CACHE() for sources under security/selinux, to simply creation
of SLAB caches.
