Ideally, we want to remove this entire series from mmotm and linux-next. It will be replaced with a simpler patch. However, before that happens I would like to address bugs in the current code as pointed out by Hugh Dickins. These are addresses in the patch which started this thread: "[PATCH] mm/hugetlbfs Fix bugs in fallocate hole punch of areas with holes" If there is a way to do this that makes your work easier let me know. It would be good if someone could take a look at this patch as these bugs also exist in 4.3. -- Mike Kravetz -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
