Thank you for pointing this.

It increases every call to kmalloc() is increased (+5 bytes) due to
passing NUMA_NO_NODE. on x86_64's defconfig, the difference of vmlinux size is not that
visible because this patch also removes tracepoint.

But yeah, increasing 5 bytes for every caller seems questionable.
I'll think about this for a bit :)

Thanks!
