with ia64, clone2() doesn't set errno to EINVAL when a zero value
is specified for child-stack parameter.
what i'd like to know:
- is clone2() code subject to change shortly?
- what should be expected when child-stack is zeroed
- where can i find a manual page ?
many thanks,

Why would you expect EINVAL in this case?

There are no plans for changes to clone2().

Not sure what you mean here.

Don't know of a man-page per se, but the ia64 linux kernel design &
implementation book has a fairly detailed description of clone2().
clone2() is really just clone() with an explicit stack-range, though.
