Merge branch 'vhost-skb-leaks'
Wei Xu says:
====================
vhost: fix a few skb leaks
Matthew found a roughly 40% tcp throughput regression with commit
c67df11f(vhost_net: try batch dequing from skb array) as discussed
in the following thread:
https://www.mail-archive.com/netdev@vger.kernel.org/msg187936.html
v4:
- fix zero iov iterator count in tap/tap_do_read()(Jason)
- don't put tun in case of EBADFD(Jason)
- Replace msg->msg_control with new 'skb' when calling tun/tap_do_read()
v3:
- move freeing skb from vhost to tun/tap recvmsg() to not
confuse the callers.
v2:
- add Matthew as the reporter, thanks matthew.
- moving zero headcount check ahead instead of defer consuming skb
due to jason and mst's comment.
- add freeing skb in favor of recvmsg() fails.
