Hi,

The main point of this series is to improve the performance for
virtio crypto:
- Use wait mechanism instead of busy polling for ctrl queue, this
  reduces CPU and lock racing, it's possiable to create/destroy session
  parallelly, QPS increases from ~40K/s to ~200K/s.
- Enable retry on crypto engine to improve performance for data queue,
  this allows the larger depth instead of 1.
- Fix dst data length in akcipher service.
- Other style fix.

lei he (2):
  virtio-crypto: adjust dst_len at ops callback
  virtio-crypto: enable retry for virtio-crypto-dev

zhenwei pi (2):
  virtio-crypto: wait ctrl queue instead of busy polling
  virtio-crypto: move helpers into virtio_crypto_common.c
