Anyway, dunno for now, if the coroutine is the only choice for block driver implementation of QEMU? If yes, probably we should go back to the QEMU version without it for the sake of code maintainability. >From the last development experience of vhost_blk that was invovled with QEMU, I don't know why people there are running the fever of introducing non-c construct like coroutine and QOM, whereas leave code untouched for inefficiency of IO performance. Anyway, I won't complaint about it again. Thanks, Yuan |
