Hey Song, I was reviewing that thread too, Are you taking a different approach based on Thomas's feedback? I think he had some fair points in that thread. My own feeling is that the buddy allocator is our tool for allocating larger variable sized physically contiguous allocations, so I'd like to see something based on that - I think we could do a hybrid buddy/slab allocator approach, like we have for regular memory allocations. I started on a slab allocator for executable memory allocations the other day (very minimal, but tested it for bcachefs and it works). But I'd love to hear more about your current approach as well. Cheers, Kent
