+Subject: [PATCH] virtio-9p: use accessor to get thread_pool
+
+The aio_context_new() function does not allocate a thread pool. This is
+deferred to the first call to the aio_get_thread_pool() accessor. It is
+hence forbidden to access the thread_pool field directly, as it may be
+NULL. The accessor *must* be used always.
+
