Hi Eddie, Vlad, and Willem, A few people mentioned to me that you guys were experiencing issues with the percpu memory allocator. I saw the talk slides mention the following two bullets: 1) allocation pattern makes the per cpu allocator reach a highly fragmented state 2) sometimes takes a long time (up to 12s) to create the PERCPU_HASH maps at startup Could you guys elaborate a little more about the above? Some things that would help: kernel version, cpu info, and a reproducer if possible? Also, I did some work last summer to make percpu allocation more efficient, which went into the 4.14 kernel. Just to be sure, is that a part of the kernel you guys are running? Thanks, Dennis
