Linus Torvalds cdd4dc3aeb Major changes: 
- Write support:
   Implemented full write support based on the classic read-only NTFS
   driver. Added delayed allocation to improve write performance through
   multi-cluster allocation and reduced fragmentation of the cluster
   bitmap.
 
 - iomap conversion:
   Switched buffered IO (reads/writes), direct IO, file extent mapping,
   readpages, and writepages to use iomap.
 
 - Remove buffer_head:
   Completely removed buffer_head usage by converting to folios.
   As a result, the dependency on CONFIG_BUFFER_HEAD has been removed
   from Kconfig.
 
 - Stability improvements:
   The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3.
   All tests passed by ntfs3 are a complete subset of the tests passed
   by this implementation. Added support for fallocate, idmapped mounts,
   permissions, and more.
 
 - xfstests Results report:
   Total tests run: 787
   Passed         : 326
   Failed         : 38
   Skipped        : 423
 
 Failed tests breakdown:
   - 34 tests require metadata journaling
   - 4 other tests:
       094: No unwritten extent concept in NTFS on-disk format
       563: cgroup v2 aware writeback accounting not supported
       631: RENAME_WHITEOUT support required
       787: NFS delegation test

Pull ntfs resurrection from Namjae Jeon:
 "Ever since Kari Argillander’s 2022 report [1] regarding the state of
  the ntfs3 driver, I have spent the last 4 years working to provide
  full write support and current trends (iomap, no buffer head, folio),
  enhanced performance, stable maintenance, utility support including
  fsck for NTFS in Linux.

  This new implementation is built upon the clean foundation of the
  original read-only NTFS driver, adding:

   - Write support:

     Implemented full write support based on the classic read-only NTFS
     driver. Added delayed allocation to improve write performance
     through multi-cluster allocation and reduced fragmentation of the
     cluster bitmap.

   - iomap conversion:

     Switched buffered IO (reads/writes), direct IO, file extent
     mapping, readpages, and writepages to use iomap.

   - Remove buffer_head:

     Completely removed buffer_head usage by converting to folios. As a
     result, the dependency on CONFIG_BUFFER_HEAD has been removed from
     Kconfig.

   - Stability improvements:

     The new ntfs driver passes 326 xfstests, compared to 273 for ntfs3.

     by this implementation. Added support for fallocate, idmapped
     mounts, permissions, and more.
