OK.  Please

a) include this info in the v2 changelog

b) consider whether you believe the fix should be backported into
   -stable kernels and if so, add a Cc: <stable@...r.kernel.org> and,
   if appropriate, add a Fixes: target

c) Place a couple of comments in the code to help readers understand
   why we're doing this

d) try to amke the changelog a little less puzzling ;)

e) retest and resend!

Thanks.
