I am still curious about the performance improvement that is with this preempt disable section compared to without it compared to !PREEMPT kernel.. If that is important then migrate_disable() would do that on RT. I guess that there were no splat with CONFIG_DEBUG_PREEMPT ? If that is all okay, please resend the patch with the explanation why this preempt_disable() does not matter and I pick it up.
