I would not even try to make these kind of changes if ntfs3 patch series

There's very little value to adding kernel-doc comments to individual
filesystems.  Filesystems don't usually provide services to the rest of
the kernel.  It's a much better use of your time to write kernel-doc
comments for functions and structures in the VFS and MM that are used
by many filesystems and device drivers.
