FYI this is needed for proper docparse formatting:

/*\
 * [Description]
 *
 * Verify that:
 *
 * 1. chown(2) returns -1 and sets errno to EPERM if the effective user id
 *    of process does not match the owner of the file and the process is not
 *    super user
 * 2. chown(2) returns -1 and sets errno to EACCES if search permission is
 *    denied on a component of the path prefix
 * 3. chown(2) returns -1 and sets errno to EFAULT if pathname points outside
 *    user's accessible address space
 * 4. chown(2) returns -1 and sets errno to ENAMETOOLONG if the pathname
 *    component is too long
 * 5. chown(2) returns -1 and sets errno to ENOENT if the specified file does
 *    not exists
 * 6. chown(2) returns -1 and sets errno to ENOTDIR if the directory component
 *    in pathname is not a directory
 * 7. chown(2) returns -1 and sets errno to ELOOP if too many symbolic links
 *    were encountered in resolving pathname
 * 8. chown(2) returns -1 and sets errno to EROFS if the named file resides on
