## Overview

In the Linux kernel, the following vulnerability has been resolved:

ntfs: treat any nonzero dio zero-range return as an error

ntfs_dio_zero_range() returns either 0 or a negative errno from
blkdev_issue_zeroout(); it never returns a positive value.  The
zeroing failure check in ntfs_attr_fallocate() therefore never fired,
so a failed zeroing operation was silently ignored: the loop kept
going, the newly allocated clusters were folded into initialized_size
and the write could succeed leaving stale on-disk data.

Treat any nonzero return as an error and abort the allocation.
