<div>
<p class="MsoNormal">Is not changing the state to TASK_INTERRUPTIBLE before calling schedule() renders it not-schedulable? I thought task would be removed off run-queue by schedule() because it is in TASK_INTERRUPTIBLE state. <o:p></o:p></p>

<div>
<p class="MsoNormal">I was making a sort of task queue. Threads puts themselves into this queue when a resource(say memory-space) is not available. And other thread, post releasing the memory space, will wake the first thread in queue.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">There are other means to achieve that, but I wondered why the above mentioned method did not succeed in making thread sleep.<o:p></o:p></p>
