Summary by cubic

Add Linux kernel 6.18+ support by migrating to the fs_context API and updating the mount path, plus inode state handling for 6.19+. Keeps compatibility with older kernels via conditional compilation; option parsing is disabled on 6.18+ for now.

• New Features

  • Implemented fs_context path: init_fs_context, get_tree, and context ops; falls back to simplefs_mount on <6.18.
  • Updated fill_super signature for >=6.18 and wired it into get_tree_bdev.
  • Switched inode state check to inode_state_read_once on >=6.19 to match struct inode_state_flags.
  • Disabled simplefs_parse_options during fill_super on >=6.18; kept parsing for <=6.17.

• Refactors

  • Formatted code and adjusted comments/includes to match the coding style; no behavior changes.
