This is simply not something that should be done. Ever.
They claimed they only made 3 patches, when in reality they probably made a lot more, and as a result, the entire bunch of contributions from this university were reverted - here’s Greg’s post about reverting almost 200 patches.
3 patches, was it ?
They targeted all from those university addresses, dating back as far as 2018 if I read it correctly -also just 15min after the 190 patch batch there were already nearly 10 kernel people saying some single patches were fine, so I guess
a) a lot will be unreverted
b) not all of those 190 were done by /these people/, just from the same uni, so I suppose the “3” figure is very much too low, but the 190 is very much too high
