Page owner function

Hi Everyone,

I would like know how to enable page owner function.

In Android phone,
need to add config as below:
CONFIG_PAGE_OWNER=y
CONFIG_PAGE_OWNER_ENABLE_DEFAULT=y

But in openwrt,
No search about this,
Is it like this:
CONFIG_KERNEL_PAGE_OWNER=y
CONFIG_KERNEL_PAGE_OWNER_ENABLE_DEFAULT=y

Thanks.

BR,
