It's probably also worth pointing out that Qualcomm have been shipping
an out of tree implementation of this as a separate module in their BSP
(originally written by Danesh Garg who's on this thread):

   https://android.googlesource.com/kernel/msm/+/android-msm-dory-3.10-kitkat-wear/drivers/md/dm-req-crypt.c

Android now wants to encrypt phones and tablets by default and have been
seeing substantial performance hits as a result, we can try to get
people to share performance data from productionish systems but it might
be difficult.
