Merge tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfsPull 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. 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"Link: https://lore.kernel.org/all/da20d32b-5185-f40b-48b8-2986922d8b25@stargateuniverse.net/ [1][ Let's see if this undead filesystem ends up being of the "Easter miracle" kind, or the "Nosferatu of filesystems" kind... ]* tag 'ntfs-for-7.1-rc1-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs: (46 commits) ntfs: remove redundant out-of-bound checks ntfs: add bound checking to ntfs_external_attr_find ntfs: add bound checking to ntfs_attr_find ntfs: fix ignoring unreachable code warnings ntfs: fix inconsistent indenting warnings ntfs: fix variable dereferenced before check warnings ntfs: prefer IS_ERR_OR_NULL() over manual NULL check ntfs: harden ntfs_listxattr against EA entries ntfs: harden ntfs_ea_lookup against malformed EA entries ntfs: check $EA query-length in ntfs_ea_get ntfs: validate WSL EA payload sizes ntfs: fix WSL ea restore condition ntfs: add missing newlines to pr_err() messages ntfs: fix pointer/integer casting warnings ntfs: use ->mft_no instead of ->i_ino in prints ntfs: change mft_no type to u64 ntfs: select FS_IOMAP in Kconfig ntfs: add MODULE_ALIAS_FS ntfs: reduce stack usage in ntfs_write_mft_block() ntfs: fix sysctl table registration and path ...

ntfs: remove redundant out-of-bound checksRemove redundant out-of-bounds validations.Since ntfs_attr_find and ntfs_external_attr_findnow validate the attribute value offsets andlengths against the bounds of the MFT record block,performing subsequent bounds checking in callerfunctions like ntfs_attr_lookup is no longer necessary.Signed-off-by: Hyunchul Lee Signed-off-by: Namjae Jeon List of files: /linux/fs/ntfs/inode.c

The Kconfig and Makefile will be added back in the final patchof this series, enabling the driver only after all features andimprovements have been applied.Acked-by: Christoph Hellwig Signed-off-by: Namjae Jeon List of files: /linux/fs/ntfs/inode.c
