[Miaohe Lin <linmiaohe@huawei.com>]

Since commit cb731d6c62bb ("vmscan: per memory cgroup slab shrinkers"),
shrink_node_slabs is renamed to drop_slab_node. And doit argument is
changed to forcekill since commit 6751ed65dc66 ("x86/mce: Fix
siginfo_t->si_addr value for non-recoverable memory faults").
