[PATCH V2 0/3] flush workers on suspend

Posted by Steve Sistare 1 year, 10 months ago

Flush to guarantee no workers are running when suspend returns,
for vdpa, vpa_sim, and vduse.  (mlx5 already does so, via the path
mlx5_vdpa_suspend -> unregister_link_notifier -> flush_workqueue.)

Steve Sistare (3):
  vhost-vdpa: flush workers on suspend
  vduse: suspend
  vdpa_sim: flush workers on suspend

Changes in V2:
  - renamed "vduse: suspend" (was vduse: flush workers on suspend)
  - call vhost_dev_flush unconditionally in "vhost-vdpa: flush workers on suspend"
