Hey Linus,

/* Summary */
This removes the old ntfs driver. The new ntfs3 driver is a full
replacement that was merged over two years ago. We've went through
various userspace and either they use ntfs3 or they use the fuse version
of ntfs and thus build neither ntfs nor ntfs3. I think that's a clear
sign that we should risk removing the legacy ntfs driver.

Quoting from Arch Linux and Debian:

* Debian does neither build the legacy ntfs nor the new ntfs3:

  "Not currently built with Debian's kernel packages, "ntfs" has been
  symlinked to "ntfs-3g" as it relates to fstab and mount commands.

  Debian kernels are built without support of the ntfs3 driver developed
  by Paragon Software."
  (cf. [2])

* Archlinux provides ntfs3 as their default since 5.15:

  "All officially supported kernels with versions 5.15 or newer are
  built with CONFIG_NTFS3_FS=m and thus support it. Before 5.15, NTFS
  read and write support is provided by the NTFS-3G FUSE file system."
  (cf. [1]).

It's unmaintained apart from various odd fixes as well. Worst case we
have to reintroduce it if someone really has a valid dependency on it.
But it's worth trying to see whether we can remove it.
