What restrictions are placed on name to inode links to simplify file system recovery?

To simplify file system recovery, restrictions on name to inode links include limiting the number of hard links a file can have, typically to a maximum of 65,536 links in many file systems. Additionally, certain special files like directories and the root directory are subject to specific rules: for instance, a directory can only have links to its entries, and the root directory must have at least one link pointing to it. These restrictions help maintain the integrity of the file system structure, making it easier to recover from inconsistencies.
