Subject: synchronize device shutdown
From: Shaohua Li <shaohua.li@xxxxxxxxx>
A patch series to make .shutdown execute asynchronously. Some drivers's
shutdown can take a lot of time. The patches can help save some shutdown
time. The patches use Arjan's async API.
This patch:
synchronize all tasks submitted by .shutdown
