The existing kthread_should_park() is used to check if the calling
kthread ('current') should park. 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.Signed-off-by: Matthias Kaehlcke <[email protected]> --- I'm not overly happy about the function name with the double underscore prefix, but couldn't come up with anything better.
