[PATCH V3 0/2] handle polling errors
This is an update version of last version to fix the handling of polling errors
in vhost/vhost_net.
Currently, vhost and vhost_net ignore polling errors which can lead kernel
crashing when it tries to remove itself from waitqueue after the polling
failure. Fix this by checking the poll->wqh before the removing and report an
error when meet polling errors.
Changes from v2:
- check poll->wqh
