While there may or may not be uses of ksm without kvm (you could run ordinary qemu, but no one would do this in a production deployment), keeping them separate helps avoid unnecessary interdependencies. For example all tlb flushes are mediated through mmu notifiers instead of ksm hooking directly into kvm. -- error compiling committee.c: too many arguments to function -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
