sched/headers: Move the 'root_task_group' declaration to <linux/sched/autogroup.h>
Also remove the duplicate declaration from <linux/init_task.h>. ( That declaration was originally duplicated for dependency hell reasons, but there's no problem including the much smaller <linux/sched/autogroup.h> header now, to pick up the right prototype. ) Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
