Srivatsa Vaddagiri dd9037a26a Fix race between attach_task and cpuset_exit ... Currently cpuset_exit() changes the exiting task's ->cpuset pointer w/o taking task_lock(). This can lead to ugly races between attach_task and cpuset_exit. Details of the races are described at http://lkml.org/lkml/2007/3/24/132. Patch below closes those races.
