I'll blame that on the "previous administration". I didn't start work on Linux until 2.3.99, and didn't take over as maintainer until 2.6.11 :-) > I don't think I have made made any mistakes in this coversion but if > people can look the code over and see if they can spot anything I would > appreciate it. I don't see any mistakes either. It builds and boots. Obviously I don't have a test case for this issue (or it would have been found long ago). > My intention is to merge this through my siginfo tree.
