well, AFAIK, the newly born child, at least when they are just about to kick in into the run queue (in any CPU), is actually still inside the parent's code path. Or in simpler word, they are still bound in the same core/processor they are created. Therefore, there's no problem regarding task struct duplication etc is that what you mean? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
