- is_ficlone_fs: use lstat+parent-dir statfs for symlinks so the symlink inode's filesystem is checked rather than the target's; also use arg (trailing-slash stripped) instead of argv[file_arg] - is_ficlone_fs: cache result per file before the waste loop to avoid redundant statfs calls on bulk removals - do_ficlone: copy extended attributes after a successful FICLONE - ficlone cross-device failure: try next waste dir on any error instead of calling exit() for non-EXDEV errno values - test_btrfs_clone: add dangling-symlink and xattr preservation tests - ci: install attr package for setfattr/getfattr in xattr tests Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
