Its not a hard prerequisite, but I explained it a little here: https://lore.kernel.org/lkml/CAA1CXcBPt4jHfH0Ggio5ghSYAQAXf08rO8R6b1faHzdjFf_Ajw@xxxxxxxxxxxxxx/ In general, the sysfs didnt really make sense without it, and given mTHPs came along right when i was working on defer, I decided to add it to mTHP too. I worked on and tested these together so it felt right to sync up the V2s for both of them. Cheers, -- Nico > > >
