Re: [PATCH] mm: Consider the entire user address space during node migration

[KOSAKI Motohiro]

Hi

Mysteriously, I haven't receive original post.
So now I'm guessing you acked following patch.

http://lkml.org/lkml/2010/5/14/393

but I don't think it is correct.

> -	check_range(mm, mm->mmap->vm_start, TASK_SIZE, &nmask,
> +	check_range(mm, mm->mmap->vm_start, TASK_SIZE_MAX, &nmask,
> 			flags | MPOL_MF_DISCONTIG_OK, &pagelist);

Because TASK_SIZE_MAX is defined on x86 only. Why can we ignore other platform?
Please put following line anywhere.

#define TASK_SIZE_MAX TASK_SIZE


But this patch is conceptually good. if it fixes the bug. I'll ack gladly.

Thanks.
