The description is a bit cryptic.  Hopefully you understand what you
mean, but does anyone else?

The code you're altering was changed two months ago by, err, you.  I
don't know if the patch still makes sense in current kernels.

Please don't raise patches against old kernels.  Please check that,
redo the patch, add a changelog which helps non-inffast.c people
understand what it does, then resend?
