Does anyone know how to patch PID namespace? as describe in this documentation? Coz I have this error. https://docs.halium.org/en/latest/porting/common-kernel-build-errors.html#undefined-reference-to-pidns-operations-on-linux-3-4

Good day guys I have a problem in making a boot img when I use mka halium-boot it will generate this error:

https://paste.ubuntu.com/p/XsBbvPk3YT/

I tried making a common.mk file and put this line of codes the same here: https://android.googlesource.com/platform/frameworks/base/+/marshmallow-release/packages/SettingsLib/common.mk

when I tried to compile again it gives me a new error:
https://paste.ubuntu.com/p/S2W4Ymsxp2/

This only happens when I use mka halium-boot but when I use mka bootimg it is successful. whats the difference of the two? Im new to porting I just started yesterday so Im really a newbee. thanks for the consideration.
