OK I guess that's fine then.

Well since you are going to potentially sleep in the middle of
an operation I'd think ablkcipher is required,

In this patch, the infrastructure needed to support multibuffer
encryption implementation is added:
a) Enhace mcryptd daemon to support blkcipher requests.
b) Update configuration to include multi-buffer encryption build support.
c) Add support to crypto scatterwalk support that can sleep
