      Wow, I had completely forgotten about that. That feels like a lifetime ago.

      Either way, reading https://lwn.net/Articles/798605/ I feel that the patch modernises the slab memory controller to suit a modern system. Which is nice.

          A slab in Australia is a carton of beer. It's summer here now, quite warm, everything's on fire, and all this talk about slabs!

              I like slabs. Reminds on the rare chance I forget, to have a beer. Prost

                Thanks, had one already. --- Even if we have 'winter', here. (Very mild, now.)
