I use 2 lcore and submit ios to the same aio bdev concurrently.
SPDK create 2 bdev_aio_io_channel(ch1 and ch2) for each lcore.
Sometimes I found that io stream stopped, and ch1->io_inflight is not 0, and rc =
epoll_wait is always 0, so it never call io_getevents again, which is the same to ch2.
SPDK is 18.10.
This patch add epoll support. Is it possible to introduce this problem?
