  docs/fs/ntfs: add mount options to support Windows native symbolic
links (2026-06-15 19:39:45 +0900)

----------------------------------------------------------------
Description for this pull request:
 - Harden handling of malformed on-disk metadata. It adds stricter
   validation for attributes, attribute lists, index roots and entries,
   EA entries, mapping pairs, and $LogFile restart areas. These changes
   fix several out-of-bounds access, integer overflow, and inconsistent
   metadata handling issues.
 - Preventing a writeback deadlock involving extent MFT records
 - Fixing resource leaks in fill_super() failure paths and the name cache
 - Serializing volume label access and improving its error handling
 - Fixing mapping-pairs decoding bounds and LCN overflow checks
 - Keeping resident index root metadata consistent during resize
 - Fixing the reported size of symbolic links
 - Avoiding an unnecessary allocation for resident inline data
 - Adds support for following and creating Windows native symbolic links.
   Relative links, absolute links, and junctions are handled, with new
   mount options controlling native symlink creation and absolute target
   translation. The existing WSL symlink behavior remains the default.
 - The unsupported quota code is removed, along with several smaller
   cleanups.
