Subject: kernel: rename is_single_threaded(task) to current_is_single_threaded(void)
X-Git-Tag: v2.6.32-rc1~737^2^2~42

kernel: rename is_single_threaded(task) to current_is_single_threaded(void)

- is_single_threaded(task) is not safe unless task == current,
  we can't use task->signal or task->mm.

- it doesn't make sense unless task == current, the task can
  fork right after the check.

Rename it to current_is_single_threaded() and kill the argument.
