Subject: [PATCH] ocfs2: remove SLAB_MEM_SPREAD flag usage

From: Chengming Zhou <zhouchengming@...edance.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.

Signed-off-by: Chengming Zhou <zhouchengming@...edance.com>
