[uml-devel] Regarding fork() implementation in UML

[Krishnappa Abhijith-A21204]

Hi,
            SORRY for bugging you guys so much...
 Regarding fork() implementation in UML
 
I was going through the below code 
 
long sys_fork(void)
{
 long ret;
 
 current->thread.forking = 1;
 ret = do_fork(SIGCHLD, UPT_SP(&current->thread.regs.regs),
        &current->thread.regs, 0, NULL, NULL);
 current->thread.forking = 0;
 return(ret);
}
 
Can pls let me know why current->thread.forking = 1 was done before
calling do_fork() and then reset after that ?
 
Regards,
Abhi
