Hmm, now that's _really_ interesting.

I think you've said to others to send patches with RFC in them when they
aren't to be applied. I sent this with RFC in, and it still got applied.

This is _really_ unfortunate, as the 0-day builder has been sending me a
stream of build errors over it, and I now have a branch with 9 patches
plus this one in fixing those errors...

And I did say in the comments below the --- that it should be left a few
days for the 0-day builder to run through it and find those errors.

Ho hum.
