- 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

Merge tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs
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.
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.
