In that case you need to think about various deadlock scenarios. An example: the P9 server needs a large order allocation while serving the buffered write request. That may trigger the page reclaim and go into synchronous writeback, possibly waiting on the exact page which the P9 server is just trying to finish writing out. This is not easy to deal with, see commit 3be5a52b for the fuse solution. I'm not saying it's the only way, there may be a better one.
