I certainly can't complain about this small code removal, but I think if we
did the kvmalloc_node() cleanup, we'd be able to get rid of even more.

For example, bucket_table_alloc() does that

        if (gfp != GFP_KERNEL)
                tbl = kzalloc(size, gfp | __GFP_NOWARN | __GFP_NORETRY);
        else
                tbl = kvzalloc(size, gfp);

purely due to the kvalloc_node() oddity. Wouldn't it be nice to just write
it as

        tbl = kvzalloc(size, gfp);

knowing that the whole point of all the kv*alloc*() functions is to "just
do the right thing given size, gpf mask, and ease of allocation".
Yes this makes a lot of sense. I'll see about adding it on top.

Thanks,
Davidlohr
