[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
