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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
