Subject: [PATCH] io_uring: Simplify the allocation of slab caches
Date: Tue, 30 Jan 2024 18:02:47 +0800 [thread overview]
Message-ID: <20240130100247.81460-1-chentao@kylinos.cn> (raw)
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.
