I try to enable whole disk encryption in 4.4 but still don't figure how to
make it work.
1. I see Nexus 7 has a partition use to hold encrypt footer
MDA -> /dev/block/mmcblk0p8
in fstab.grouper
wait,encryptable=/dev/block/platform/sdhci-tegra.3/by-name/MDA
What is this partition for and what is its format and how large is
required?
2. When I try encrypt my /data partition, I got the following kernel
message:
[ 145.763294] device-mapper: table: 254:0: crypt: Device lookup failed
[ 145.769859] device-mapper: ioctl: error adding target to table
Does this means some configs missing in my kernel?
Any help would be appreciated.
