Subject: [PATCH] vdpa:Fix dirty page bitmap synchronization not done after
|
||
|
|
suspend for vdpa devices
|
||
|
|
|
||
|
|
Change the flag for vdpa device to determine whether to perform log_sync
|
||
|
|
from dev->start to dev->log, and do not release dev->log after vdpa device
|
||
|
|
suspend, and release it uniformly by vhost_dev_stop.
