Subject: [PATCH] io_uring: Simplify the allocation of slab caches
Date: Tue, 30 Jan 2024 18:02:47 +0800

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.
