Ah, the quick fix is to "Enable kernel namespaces" and
"User namespaces" in the Global build setting of LEDE's
config. Just check that the following options are present in
the .config file:

CONFIG_KERNEL_NAMESPACES=y
CONFIG_KERNEL_USER_NS=y

This error is caused by the #ifdef in the compat code. As of
commit "cred/userns: define current_user_ns() as a function" [0]
the current_user_ns is no longer a macro in the !CONFIG_USER_NS
case, so the code tries to define it (but this is not needed as
there's a static inline function for it).

Anyway, I put a crude ifdef guard around it for now. Let's see
what else breaks.

Not that I know, but if you are going on a buying spree, you could
also look into the Zyxel NBG6617 (has no public sources either). 
Netgear has published sources for their RBR50 / RBS50 (Orbi) right 
here[1].
