No, dup_mm tries to copy memory of the current task into the new task.



But we see this message in kern.log:
Xorg:2967 map pfn expected mapping type write-back for d0000000-e0000000, got write-combining

This comes from reserve_pfn_range in arch/x86/mm/pat.c.




In another note:

I was able to do a kernel compilation with the kernel under xen that couldn't run
the X server due to this forking problem.
