Hi folks,

[I am resending to fix the broken thread in the previous one.]

This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk
device accelerator. Compared to userspace virtio-blk implementation, vhost-blk
gives about 5% to 15% performance improvement.

Asias He (5):
  aio: Export symbols and struct kiocb_batch for in kernel aio usage
  eventfd: Export symbol eventfd_file_create()
  vhost: Make vhost a separate module
  vhost-net: Use VHOST_NET_FEATURES for vhost-net
  vhost-blk: Add vhost-blk support
