Flush to guarantee no workers are running when suspend returns, for vdpa, vdpa_sim, and vduse. (mlx5 already does so, via the path mlx5_vdpa_suspend -> unregister_link_notifier -> flush_workqueue.) Changes in V2: - renamed "vduse: suspend" (was vduse: flush workers on suspend) - call vhost_dev_flush unconditionally in "vhost-vdpa: flush workers on suspend" Changes in v3: - rewrote vdpa_sim patch Steve Sistare (3): vhost-vdpa: flush workers on suspend vduse: suspend vdpa_sim: flush workers on suspend drivers/vdpa/vdpa_sim/vdpa_sim.c | 16 ++++++++++++++-- drivers/vdpa/vdpa_sim/vdpa_sim.h | 1 + drivers/vdpa/vdpa_user/vduse_dev.c | 24 ++++++++++++++++++++++++ drivers/vhost/vdpa.c | 3 +++ 4 files changed, 42 insertions(+), 2 deletions(-) -- 2.39.3
