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.
