Kernel 5.4.70 fscrypt using yocto build

[RayC]

Hi,

Our linux kernel version is 5.4.70 and we're trying to use fscrypt on the imx6ul target.

I check "FS_ENCRYPTION" on menuconfig editor and bitbake the kernel image again.

I see yocto takes some time to finish (with no errors) but the image still doesn't have "fscrypt" command in it.

Maybe "fscrypt" user command is not part of FS_ENCRYPT?

Can someone help on how to add fscrypt user command to my image? Do I need to add a yocto package? 

Thanks,

Ray

Also, please look at section 10.5 (Disk encryption acceleration)
