[Qemu-devel] [PATCH 03/11] qemu-sockets: make wait_for_connect be invoke


From: MORITA Kazutaka
Subject: [Qemu-devel] [PATCH 03/11] qemu-sockets: make wait_for_connect be invoked in qemu_aio_wait
Date: Tue, 23 Jul 2013 17:30:13 +0900

This allows us to use inet_nonblocking_connect() and
unix_nonblocking_connect() in block drivers.

qemu-ga needs to link block-obj to resolve dependencies of
qemu_aio_set_fd_handler().
