The patch titled
kthread_bind: use wait_task_inactive(TASK_UNINTERRUPTIBLE)
has been removed from the -mm tree. Its filename was
kthread_bind-use-wait_task_inactivetask_uninterruptible.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: kthread_bind: use wait_task_inactive(TASK_UNINTERRUPTIBLE)
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Now that wait_task_inactive(task, state) checks task->state == state,
we can simplify the code and make this debugging check more robust.
