From: Greg Kurz Subject: [PATCH] virtio-9p: use accessor to get thread_pool Date: Sun, 20 Dec 2015 12:19:05 +0100 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.
