> Why did it get removed from the kernel? Allegedly, there were security problems with it. I think the kernel people had a program which fired random inputs at lots of components, and noted when things went wrong; and things went wrong in the scroll back component. And they couldn't find anybody to look into these problems. That's the official position. I'm a bit more cynical about it. > If you want to get it back in, couldn't you ping Greg KH and get some > help - or even just advice - getting it accepted? I have no reason to believe all the "security problems" will have been resolved by my hacking. I took the algorithmic bits from 4.19.97 basically unchanged. Maybe there's not much enthusiasm for this feature, in which case I will keep it working for myself. Linux is basically unusable to me without it. There are probably quite a few patches to restore the scrollback floating around the web by now: the changes were not particularly difficult to anybody who knows the code, but getting to know the code was unusually difficult. We'll see how people react to it here, first. > Cheers, > Wol -- Alan Mackenzie (Nuremberg, Germany).
