    Subject[PATCH 5.7 022/244] cgroup: Fix sock_cgroup_data on big-endian.
    Date
    From: Cong Wang <xiyou.wangcong@gmail.com>

    [ Upstream commit 14b032b8f8fce03a546dcf365454bec8c4a58d7d ]

    In order for no_refcnt and is_data to be the lowest order two
    bits in the 'val' we have to pad out the bitfield of the u8.

    Fixes: ad0f75e5f57c ("cgroup: fix cgroup_sk_alloc() for sk_clone_lock()")
