Summary by cubic

Add Linux kernel 6.18+ support by moving to the fs_context API and updating mount and inode handling. Backward compatible; option parsing is off on 6.18+ for now, and coding style issues are fixed.

• New Features

  • Implement fs_context path: get_tree and init_fs_context hook; fallback to simplefs_mount on <6.18.
  • Update fill_super signature for >=6.18; wire into get_tree_bdev.
  • Use inode_state_read_once on >=6.19 for the updated inode_state layout.
  • Disable simplefs_parse_options in fill_super on >=6.18; keep parsing on <=6.17.

• Refactors

  • Fixed coding style errors and aligned comments/includes; no behavior changes.
