A good part of software engineering (and FOSS in general) is collaboration. People have their own work responsibilities & personal lives. If you had questions, you could've raised them on-list or directly to Lorenzo and could've helped him drive it forward (which he is, and he's posting careful precursor patches). > > If there are technical issues, please point them out directly. > Or is this simply how technical discussions are usually conducted in the Linux community or the mm subsystem? There is no technical discussion to be had. Lorenzo is doing a large, careful rework of anon rmap (and rmap in general). You don't get to override his work because you decided to ignore the "community outreach and collaboration" step. -- Pedro
