Hi Michael,

Thanks for your mail. However, the dead code has resulted from
another bug in the code, we should be decrementing retry instead
of i. The same bug occurs in several other places in the code too.

So I would say don't apply this patch. We are planning a series of
patches to fix other issues in the code when the 3.13 merge window
closes and will include this fix too and include you in "Reported-by".

Thanks,
Ashutosh
