What is "earlier clone()"?

clone() doesn't have stack size info which was added to clone3().

/me goes and reads the manpage...

    clone3()
        The  clone3()  system call provides a superset of the functionality of the older
        clone() interface.  It also provides a number of  API  improvements,  including:
        space  for additional flags bits; cleaner separation in the use of various argu‐
        ments; and the ability to specify the size of the child's stack area.

Aha, Yu-cheng, pls use those words to make your comment understandable.

Thx.


Sure!
