Hmm. I only now noticed that that commit is over two years old. So I think it's still wrong (clearly others do change passwords outside of listening state), but considering that it apparently took people two years to notice, at least some of the onus on figuring out a better morel is on people who didn't even bother to test things in a timely manner. At some point "entreprise vendor kernels" or whatever who stay with legacy kernels for a long time only have themselves to blame. Linus
