net: bridge: Use KMEM_CACHE instead of kmem_cache_create

[PATCH net-next] net: bridge: Use KMEM_CACHE instead of kmem_cache_create

Posted by Kunwu Chan 1 year, 10 months ago

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.

Same remark as to the previous patch, the name would change.
