I'm currently discovering what version control systems are for. :-( Even though I've only posted two or three versions of my patch, I'm already having difficulty keeping track of it. I no longer believe keeping the patch informally is going to work. I think I'm going to have to clone the git repository of the kernel (about which I'm going to ask on another thread). Anyhow, back to the topic. There's no URL with my patch; it's purely posted on gentoo-users. Maybe I should put it into the Gentoo wiki. But first, I must get it into a proper VCS. As for the two(?) versions of my patch, they differed mainly in the aesthetics - diff.20210405.diff had lots of ugly maintainer comments in it. So, could I ask you please to try that 1-hunk patch I posted yesterday on top of the version you have. Please then tell me whether or not it works. I am going to get this unsystematic muddle sorted out. > Thanks, > Jorge Almeida -- Alan Mackenzie (Nuremberg, Germany).
