Subject: [PATCH] ceph: remove SLAB_MEM_SPREAD flag usage
Date: Sat, 24 Feb 2024 13:47:15 +0000	[thread overview]
Message-ID: <20240224134715.829225-1-chengming.zhou@linux.dev> (raw)

From: Chengming Zhou <zhouchengming@bytedance.com>

The SLAB_MEM_SPREAD flag is already a no-op as of 6.8-rc1, remove
its usage so we can delete it from slab. No functional change.
