Shuhei Matsumoto 8753fdb645 example/nvmf: Run SPDK threads by FIFO to avoid deadlock ... if spdk_thread_poll() calls spdk_thread_create() to create SPDK thread dynamically, it will acquire nvmf_reactor->mutex and will cause deadlock because the queue nvmf_reactor->threads is accessed by any POSIX thread by holding nvmf_reactor->mutex. If any non-owner POSIX thread manipulate nvmf_reactor->threads by holding nvmf_reactor->threads, like general priority based scheduler, running SPDK threads by FIFO will be better. Change nvmf_reactor_run() to dequeue a SPDK thread from the head, run it, and then enqueue it to the tail. Release nvmf_reactor->mutex while spdk_thread_poll() is executed.
