kernel memory allocation

From [1] I'm lead to believe the only difference between the regular kmalloc() arguments and those of kmalloc_node() is the one specifying which node you want to allocate the memory on.

Aside from the third argument, which seems to be related with NUMA (with which I never worked on kernel-context), I would suggest you to read [2].

If on the other hand you only want to allocate memory locally, maybe you should use kmalloc() or one of its variants [3].
