commit e95113ed4d428219e3395044e29f5713fc446720 upstream.
If size of file was reduced, we still kept allocated blocks. This commit makes ntfs3 work as other fs like btrfs. Link: https://bugzilla.kernel.org/show_bug.cgi?id=214719 Fixes: 4342306f0f0d ("fs/ntfs3: Add file operations and implementation")
