Well, in that particular trace we are not waiting for PageLock but on PageWriteback bit as I wrote. But otherwise yes, NFS set PageWriteback bit and sent the data from the page to the server. When the server responds, the PageWriteback bit will get cleared and could continue. But the response didn't come.

Well, in that particular trace we are not waiting for PageLock but on PageWriteback bit as I wrote. But otherwise yes, NFS set PageWriteback bit and sent the data from the page to the server. When the server responds, the PageWriteback bit will get cleared and could continue. But the response didn't come.
