Parameter:

Type	Parameter	Name
struct task_struct *	p
const struct cpumask *	new_mask

1600

If Not pumask_test_cpu - test for a cpu in a cpumask*@cpu: cpu number (< nr_cpu_ids)*@cpumask: the cpumask pointer* Returns 1 if @cpu is set in @cpumask, else returns 0 Then Return -EINVAL

1602

Return 0

apm_power_off	apm_power_off - ask the BIOS to power off* Handle the power off sequence

worker_attach_to_pool	worker_attach_to_pool() - attach a worker to a pool@worker: worker to be attached@pool: the target pool* Attach @worker to @pool. Once attached, the %WORKER_UNBOUND flag and* cpu-binding of @worker are kept coordinated with the pool across

housekeeping_affine
rcu_perf_reader	RCU perf reader kthread. Repeatedly does empty RCU read-side* critical section, minimizing update-side interference.
rcu_perf_writer	RCU perf writer kthread. Repeatedly does a grace period.
update_tasks_cpumask	pdate_tasks_cpumask - Update the cpumasks of tasks in the cpuset.@cs: the cpuset in which each task's cpus_allowed mask needs to be changed Iterate through each task of @cs updating its cpus_allowed to the* effective cpuset's
cpuset_attach
cpuset_fork	Make sure the new task conform to the current state of its parent,* which could have been changed by cpuset just after it inherits the* state from the parent and before it sits on the cgroup's task list.
torture_shuffle_tasks	Shuffle tasks such that we allow shuffle_idle_cpu to become idle.* A special case is when shuffle_idle_cpu = -1, in which case we allow* the tasks to run on all CPUs.
rest_init
kswapd	The background pageout daemon, started as a kernel thread* from the init process.* This basically trickles out pages so that we have _some_* free memory available even if there is no other activity* that frees anything up
kswapd_cpu_online	It's optimal to keep kswapds on the same CPUs as their memory, butnot required for correctness. So if the last cpu in a node goesaway, we get changed to run anywhere: as the first one comes back,restore their cpu bindings.
