Allegedly, there were security problems with it. I think the kernel |
13 |
people had a program which fired random inputs at lots of components, |
14 |
and noted when things went wrong; and things went wrong in the scroll |
15 |
back component. And they couldn't find anybody to look into these |
16 |
problems. |

That's the official position. I'm a bit more cynical about it. |

I have no reason to believe all the "security problems" will have been |
24 |
resolved by my hacking. I took the algorithmic bits from 4.19.97 |
25 |
basically unchanged. |

Maybe there's not much enthusiasm for this feature, in which case I will |
28 |
keep it working for myself. Linux is basically unusable to me without |
29 |
it. There are probably quite a few patches to restore the scrollback |
30 |
floating around the web by now: the changes were not particularly |
31 |
difficult to anybody who knows the code, but getting to know the code |
32 |
was unusually difficult. |

We'll see how people react to it here, first. |
