Hi, I'd like to propose a session about the next steps for SLUB. This is different from the BOF about sheaves that Matthew suggested, which would be not suitable for the whole group due to being not fleshed out enough yet. But the session could be scheduled after the BOF so if we do brainstorm something promising there, the result could be discussed as part of the full session. Aside from that my preliminary plan is to discuss: - what was made possible by reducing the slab allocators implementations to a single one, and what else could be done now with a single implementation - the work-in-progress work (for now in the context of maple tree) on SLUB per-cpu array caches and preallocation - what functionality would SLUB need to gain so the extra caching done by bpf allocator on top wouldn't be necessary? (kernel/bpf/memalloc.c) - similar wrt lib/objpool.c (did you even noticed it was added? :) - maybe the mempool functionality could be better integrated as well? - are there more cases where people have invented layers outside mm and that could be integrated with some effort? IIRC io_uring also has some caching on top currently... - better/more efficient memcg integration? - any other features people would like SLUB to have? Thanks, Vlastimil
