    Pull ntfs updates from Namjae Jeon:
     "This contains improvements to compression support, metadata handling,
      error propagation, and filesystem robustness.

      New feature:

       - Add optional read support for Windows System Compression (WOF)

         Add CONFIG_NTFS_FS_WOF_COMPRESSION and support reading
         WOF-compressed files through the NTFS page-read path. This includes
         parsing REPARSE_TAG_WOF, handling resident and non-resident WOF
         metadata and compressed chunks, and adding kernel-side XPRESS
         4K/8K/16K and LZX 32K decompressors. The codecs use a common
         transparent compression interface shared with LZNT1.

         WOF support is read-only and disabled unless explicitly enabled.

      Other changes:

       - Harden malformed filesystem handling and error paths.

         Add bounds and consistency checks for mapping pairs, run lengths,
         MFT locations, update-sequence offsets, non-resident attributes,
         compressed attributes, index roots, and bitmap scans. Prevent
         out-of-bounds accesses in decompression, MFT allocation, and index
         conversion paths, clean up MFT mappings and attribute search
         contexts on failure, and propagate attribute and inode
         initialization errors correctly.

       - Improve compressed-file I/O path.

         Fix compressed writes on large-page and highmem systems, reuse
         compression contexts and output workspaces, avoid unnecessary reads
         for full-unit overwrites, and submit one bio per compressed write
         unit. Write replacement data before publishing the new mapping,
         correctly handle zero-filled compressed blocks, and fix
         initialized-size and folio state updates after compressed writes.

       - Synchronize resident reads with MFT record updates.

       - Validate the final EA stream size before modifying existing data,
         rewrite the stream safely when replacing entries, restore the
         previous state when metadata updates fail, and remove the EA
         attribute pair when the last entry is deleted.

       - Apply Windows filename restrictions only when windows_names is
         enabled.

       - Allow index roots to relocate to extent MFT records when the base
         record lacks sufficient space.

       - Move non-resident attribute payload data before shrinking its
         record.

       - Correct resident-to-non-resident conversion when compression or
         sparse flags are enabled.

       - Prepare file allocation and initialized-size updates before
         buffered or direct I/O submission, and use
         pagecache_isize_extended() when extending the file size.

       - Fix highmem and page/folio access in compressed I/O paths by using
         the correct local mappings and page helpers.

       - Apply per-file $LXMOD permissions instead of mount masks when
         available, and prevent unprivileged writes to reserved $LX*
         attributes

       - Update the NTFS maintainer mailing list

       - Small cleanups"
