Hi Kees, Today's linux-next merge of the kspp tree got a conflict in: virt/kvm/kvm_main.c between commit: 46bea48ac241 ("kvm, mm: account kvm related kmem slabs to kmemcg") from the kvm tree and commit: 67ac5ee34976 ("kvm: whitelist struct kvm_vcpu_arch") from the kspp tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc virt/kvm/kvm_main.c index fe080f5152b6,1075d7338807..000000000000 --- a/virt/kvm/kvm_main.c +++ b/virt/kvm/kvm_main.c @@@ -4006,8 -4009,11 +4006,12 @@@ int kvm_init(void *opaque, unsigned vcp /* A kmem cache lets us meet the alignment requirements of fx_save. */ if (!vcpu_align) vcpu_align = __alignof__(struct kvm_vcpu); - kvm_vcpu_cache = kmem_cache_create("kvm_vcpu", vcpu_size, vcpu_align, - SLAB_ACCOUNT, NULL); + kvm_vcpu_cache = + kmem_cache_create_usercopy("kvm_vcpu", vcpu_size, vcpu_align, - 0, offsetof(struct kvm_vcpu, arch), ++ SLAB_ACCOUNT, ++ offsetof(struct kvm_vcpu, arch), + sizeof_field(struct kvm_vcpu, arch), + NULL); if (!kvm_vcpu_cache) { r = -ENOMEM; goto out_free_3;
