You mean async crypto with 10 stacked devices? Find me a single
user who does that.
Traditionally stacking didn't work very
well in the kernel due to the limited kernel stack overflows.
I don't think that's significantly different here.
Anyways stacking could be probably fixed, but it's also that 99.999999%
of all dm-crypt users don't stack or use async but simply need a
scalable dm-crypt. Extreme stacking is extremly low on the
priority list.
Right now dm-crypt seems to have other problems anyways that need
to be addressed first.
