Bruce,
It looks like AKPM has taken the kzalloc_node patch into -mm. I'd
like to have you take this set into your tree at some point, but don't
want you to have to carry that VM patch too. Would you be amenable to me
changing the above to something like:
/* FIXME: change to kzalloc_node when/if it makes it to mainline */
rqstp = kmalloc_node(sizeof(*rqstp), GFP_KERNEL | __GFP_ZERO, node);
...and then we can make the FIXME change when mainline has the new inline?
Thanks,
