    hwpoison: use page_cgroup_ino for filtering by memcg · 94a59fb3
    Vladimir Davydov authored
    Hwpoison allows to filter pages by memory cgroup ino.  Currently, it
    calls try_get_mem_cgroup_from_page to obtain the cgroup from a page and
    then its ino using cgroup_ino, but now we have a helper method for
    that, page_cgroup_ino, so use it instead.
    This patch also loosens the hwpoison memcg filter dependency rules - it
    makes it depend on CONFIG_MEMCG instead of CONFIG_MEMCG_SWAP, because
    hwpoison memcg filter does not require anything (nor it used to) from
