[PATCH 0/6] vhost code cleanup and minor enhancement

Hi all:

This series tries to unify and simplify vhost codes especially for zerocopy.

Plase review.

Thanks

Jason Wang (6):
  vhost_net: make vhost_zerocopy_signal_used() returns void
  vhost_net: use vhost_add_used_and_signal_n() in
    vhost_zerocopy_signal_used()
  vhost: switch to use vhost_add_used_n()
  vhost_net: determine whether or not to use zerocopy at one time
  vhost_net: poll vhost queue after marking DMA is done
  vhost_net: remove the max pending check
