This flag is used to indicate to the callees that this allocation will be
serviced to the kernel. It is not supposed to be passed by the callers
of kmem_cache_alloc, but rather by the cache core itself.

Not sure what "serviced to the kernel" means, does this mean that the
memory will not be accounted for to the root memcg?

In this context, it means that is a kernel allocation, not a userspace 
one (but in process context, of course), *and* it is to be accounted a
specific memcg.
