slub,rcu: don't assume the size of struct rcu_head The size of struct rcu_head may be changed. When it becomes larger, it will pollute the page array. We reserve some some bytes for struct rcu_head when a slab is allocated in this situation. Changed from V1: use VM_BUG_ON instead BUG_ON Acked-by: Christoph Lameter <cl@linux.com> Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Pekka Enberg <penberg@kernel.org>
