I'm for creating a new allocator that will replace module_alloc(). This will give us a clean abstraction that modules and all the rest will use and it will make easier to plug binpack or another allocator instead of vmalloc. Another point is with a new allocator we won't have weird dependencies on CONFIG_MODULE in e.g. bpf and kprobes. I'll have something ready to post as an RFC in a few days. > Thanks, > Song -- Sincerely yours, Mike.
