There is a bug sending link commands for existing file paths. When we're processing an inode, we go over all references. All the new file paths are added to the "new_refs" list. And all the deleted file paths are added to the "deleted_refs" list. In the end, when we finish processing the inode, we iterate over all the items in the "new_refs" list and send link commands for those file paths. After that, we go over all the items in the "deleted_refs" list and send unlink commands for them. If there are duplicated file paths in both lists, we will try to create them before we remove them. Then the receiver gets an -EEXIST error when trying the link operations.
