Waiman Long 243d9f3a11 cgroup/cpuset: Add cpuset_can_fork() and cpuset_cancel_fork() methods
[ Upstream commit eee8785379 ]

In the case of CLONE_INTO_CGROUP, not all cpusets are ready to accept
new tasks. It is too late to check that in cpuset_fork(). So we need
to add the cpuset_can_fork() and cpuset_cancel_fork() methods to
pre-check it before we can allow attachment to a different cpuset.

We also need to set the attach_in_progress flag to alert other code
that a new task is going to be added to the cpuset.

Fixes: ef2c41cf38 ("clone3: allow spawning processes into cgroups")
