But how does the thread which calls mempool_put() get hold of the memory buffers that were obtained using mempool_get() by some other thread? Or this is not the scenario you are worrying about? Is it rather that multiple threads independently call mempool_get() and then mempool_put() on their own buffers? And you are worried that a thread will fail to return (mempool_put) a buffer that it earlier allocated (mempool_get)? We could create a litmus test for that.
