From 4b3a4f2d458ca5a7c6c16ac36a8d9ac22cc253d6 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Wed, 23 Dec 2015 10:56:58 +0100 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.
