kthread: Add __kthread_should_park()
kthread_should_park() is used to check if the calling kthread ('current')
should park, but there is no function to check whether an arbitrary kthread
should be parked. The latter is required to plug a CPU hotplug race vs. a
parking ksoftirqd thread.
The new __kthread_should_park() receives a task_struct as parameter to
check if the corresponding kernel thread should be parked.
Call __kthread_should_park() from kthread_should_park() to avoid code
duplication.
