Hi, Ingo,

For cpuset subsystem, this filed is nonzero; for other subsystems, this is zero.
Actually none of these subsystem will change this field,  I just
thought that  this is
a little subtle. as the comment in patches says, this is mainly for
document reason
to inform other maintainers that css_alloc implementation should be
taken care of ,
depending on this field is zero or not.

Thanks,
Jianyu Zhan
