oh, I see, i miss them, but i have a new question:

I have set CONFIG_FS_ENCRYPTION and CONFIG_EXT4_ENCRYPTION both y, but
after build the config do not include them, and what make me confused

Did i miss some dependence kconfigs or conflict kconfigs?

You can use "make menuconfig" to help figure out what you missed.
