Subject: [PATCH] btrfs: remove SLAB_MEM_SPREAD flag usage
Date: Sat, 24 Feb 2024 13:47:09 +0000
Message-Id: <20240224134709.829191-1-chengming.zhou@linux.dev>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

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.
