Probably worth mentioning something like

"guest_memfd wants to implement support for NUMA policies just like 
shmem already does using the shared policy infrastructure. As 
guest_memfd currently resides in KVM module code, we have to export the 
relevant symbols.

In the future, guest_memfd might be moved to core-mm, at which point the 
symbols no longer would have to be exported. When/if that happens is 
still unclear."
