Subject: RE: [RESEND PATCH v2 1/4] mm/hwpoison: fix traverse hugetlbfs page
 to avoid printk flood

This is good - but the real solution is to stop poisoning entire huge pages ... they should
be broken into 4K pages and just one 4K page should be poisoned.

Naoya Horiguchi: I thought that you were looking at this problem some months ago. Any progress?
