AFAIK, it's a guard for loop descriptors.

this patch is to add the support for vdpa tool in vp_vdpa
here is the example steps
modprobe vp_vdpa
modprobe vhost_vdpa

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 t
Use temporary variable to make code easy to read and maintain.
/* Pad cipher's parameters */
vcrypto->ctrl.u.sym_create_session.op_type =
cpu_to_le32(VIRTIO_CRYPTO_SYM_OP_CIPHER);
vcrypto->ctrl.u.sym_create_session.u.cipher.para.algo =
vcrypto
Originally, all of the control requests share a single buffer(
ctrl & input & ctrl_status fields in struct virtio_crypto), this
allows queue depth 1 only, the performance of control queue gets
limited by this design.
In this patch, each request allocates request buffer dynamically, and
free buffer
Originally, after submitting request into virtio crypto control
queue, the guest side polls the result from the virt queue. This
works like following:
CPU0 CPU1 ... CPUx CPUy

For some akcipher operations(eg, decryption of pkcs1pad(rsa)),
the length of returned result maybe less than akcipher_req->dst_len,
we need to recalculate the actual dst_len through the virt-queue
protocol.

Enable retry for virtio-crypto-dev, so that crypto-engine
can process cipher-requests parallelly.
