Thanks.

When cookie gets withdrawn, Cachefiles will send a CLOSE request to user daemon, telling that the associated anon_fd could be closed. But it's just a hint. User daemon could keep the anon_fd open when it receives the CLOSE request. After sending the CLOSE request, Cachefiles will go on the process of withdrawing cookie and won't wait for a reply synchronously. So CLOSE request is just a hint to user daemon, and it doesn't need to be replied.
-- Thanks, Jeffle
