The original use of strcpy suggests that the string must be \0 terminated. I

You are right, the iterator's name pointer always points to a \0 terminated
string, but also always points to one shorter than FS_DIRENT_NAME_LEN.

The on-disk fields are not \0 terminated, but the code extracting them
deals with it properly. If the length would overflow, a NULL instead
of a dir_entry * is returned, so while it is not obvious, AFAICT the
original code is fine.

Thanks Martin, we can drop this patch.
