Applied, but I still had to fix up a bunch of details :-(

+		ca->undo_last_cong = 0;  

That line had trailing whitespace.

+	case TCP_CA_Open: 

That one too.

+        		if (ca->undo_last_cong) { 

That line had an initial set of space characters, instead
of pure leading tab characters.

+				ca->last_cong = jiffies;   

More trailing whitespace.

+		break;	

And some more trailing whitespace.
