Why is fork1() exported from hotspot? (original) (raw)

Hi all,

on Linux we define and export "fork1()" - a stub for fork() - and "fork1" also appears in linker mapfiles for bsd and AIX. The latter, I am sure, is just a copy-paste-effect.

Why do we need to define and export fork1() for non-solaris platforms? We only ever use it on Solaris.

The comment in os_linux.cpp is not really enlightening: "// Something to do with the numa-aware allocator needs these symbols"

Does anyone know why this is needed?

Regards, Thomas
