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. + +Fixes: ebac1202c95a4f1b76b6ef3f0f63926fa76e753e +Reviewed-by: Michael Tokarev <mjt@tls.msk.ru> +Tested-by: Michael Tokarev <mjt@tls.msk.ru> +Cc: qemu-stable@nongnu.org +Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> +--- + hw/9pfs/virtio-9p-coth.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/hw/9pfs/virtio-9p-coth.c b/hw/9pfs/virtio-9p-coth.c +index fb6e8f8..ab9425c 100644 +--- a/hw/9pfs/virtio-9p-coth.c ++++ b/hw/9pfs/virtio-9p-coth.c +@@ -36,6 +36,6 @@ static int coroutine_enter_func(void *arg) + void co_run_in_worker_bh(void *opaque) + { + Coroutine *co = opaque; +- thread_pool_submit_aio(qemu_get_aio_context()->thread_pool, ++ thread_pool_submit_aio(aio_get_thread_pool(qemu_get_aio_context()), + coroutine_enter_func, co, coroutine_enter_cb, co); + } +-- +2.6.3 + |
