It appears like the time_attrs parameter of security_path_truncate is
unused by any security module, so I wonder if we can remove it?

We cannot really get it right for truncate(2) calls anyway without
holding i_mutex over the call (because ATTR_MTIME|ATTR_CTIME is
effectively set iff size changes). So the meaning of this parameter
today is misleading anyway.

Thanks,
Nick
