Merge tag 'ntfs3_for_6.12' of https://github.com/Paragon-Software-Group/linux-ntfs3HEADmaster

Pull ntfs3 updates from Konstantin Komarov:
"New:
   - implement fallocate for compressed files
   - add support for the compression attribute
   - optimize large writes to sparse files

 Fixes:
   - fix several potential deadlock scenarios
   - fix various internal bugs detected by syzbot
   - add checks before accessing NTFS structures during parsing
   - correct the format of output messages

  Refactoring:
   - replace fsparam_flag_no with fsparam_flag in options parser
   - remove unused functions and macros"
