Xi Wang 1ecd3c7ea7 nilfs2: avoid overflowing segment numbers in nilfs_ioctl_clean_segments() ... nsegs is read from userspace. Limit its value and avoid overflowing nsegs * sizeof(__u64) in the subsequent call to memdup_user(). This patch complements 481fe17e97 ("nilfs2: potential integer overflow in nilfs_ioctl_clean_segments()").
