From 14b032b8f8fce03a546dcf365454bec8c4a58d7d Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Thu, 9 Jul 2020 16:28:44 -0700 Subject: [PATCH] cgroup: Fix sock_cgroup_data on big-endian. 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()") Reported-by: Guenter Roeck Signed-off-by: David S.
