Sorry, I fixed it with a code simplification (I thought the while loop
wasn't needed at all), but when you explained why in fact we still
needed it, I dropped my commit, and forgot that this also dropped the
fix which silenced the warning.  I'll grab your patch and included
with any other fixes that we might need for this merge window.

Linus, are you in a hurry to get this fixed up?  It's a false warning
on gcc's part, so it's not actually causing any actual problems.  If
not, I can wait until a week or so to see if there are any other bug
fixes that are required and push the fix to you towards the end of the
merge window.
