Hi, Michael
I would appreciate it if you could review this series!

v5 -> v6:
- Minor fix for crypto_engine_alloc_init_and_set().
- All the patches have been reviewed by Gonglei, add this in patch.
Thanks to Gonglei.
v4 -> v5:
- Fix potentially dereferencing uninitialized variables in
'virtio-crypto: use private buffer for control request'.
Thanks to Dan Carpenter!
v3 -> v4:
- Don't create new file virtio_common.c, the new functions are added
into virtio_crypto_core.c
- Split the first patch into two parts:
1, change code style,
2, use private buffer instead of shared buffer
- Remove relevant change.
- Other minor changes.
v2 -> v3:
- Jason suggested that spliting the first patch into two part:
1, using private buffer
2, remove the busy polling
Rework as Jason's suggestion, this makes the smaller change in
each one and clear.
v1 -> v2:
- Use kfree instead of kfree_sensitive for insensitive buffer.
- Several coding style fix.
- Use memory from current node, instead of memory close to device
- Add more message in commit, also explain why removing per-device
request buffer.
- Add necessary comment in code to explain why using kzalloc to
allocate struct virtio_crypto_ctrl_request.
v1:
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 (3):
virtio-crypto: change code style
virtio-crypto: use private buffer for control request
virtio-crypto: wait ctrl queue instead of busy polling
