In the Linux kernel, the following vulnerability has been resolved: cgroup:
Add missing cpus_read_lock() to cgroup_attach_task_all() syzbot is hitting
percpu_rwsem_assert_held(&cpu_hotplug_lock) warning at cpuset_attach() [1],
for commit 4f7e7236435ca0ab (“cgroup: Fix threadgroup_rwsem <->
cpus_read_lock() deadlock”) missed that cpuset_attach() is also called from
cgroup_attach_task_all(). Add cpus_read_lock() like what
cgroup_procs_write_start() does.
