But then why was the task migration notifier even in Jeremy's original code for Xen? Was it supposed to work even on non-synchronized TSC?
If that's the case, then it could be reverted indeed; but then why did you commit this patch to 4.1? Did you think of something that would cause the seqcount-like protocol to fail, and that turned out not to be the case later? I was only following the mailing list sparsely in March.
