Hi all,
After merging the cgroup tree, today's linux-next build (x86_64
allmodconfig) failed like this:
In file included from <command-line>:
kernel/cgroup/cgroup.c: In function 'cgroup_free_root':

Possibly caused by commit
77070eeb8821 ("cgroup: Avoid false cacheline sharing of read mostly rstat_cpu")
I have used the cgroup tree from next-20231206 for today.
