[Devel] [PATCH 6/6] KVM: async_pf: Let guest support delivery of async_pf from guest mode

From: Wanpeng Li Adds another flag bit (bit 2) to MSR_KVM_ASYNC_PF_EN. If bit 2 is 1, async page faults are delivered to L1 as #PF vmexits; if bit 2 is 0, kvm_can_do_async_pf returns 0 if in guest mode. This is similar to what svm.c wanted to do all along, but it is only

[Devel] [PATCH 3/6] KVM: async_pf: Force a nested vmexit if the injected #PF is async_pf

From: Wanpeng Li Add an nested_apf field to vcpu->arch.exception to identify an async page fault, and constructs the expected vm-exit information fields. Force a nested VM exit from nested_vmx_check_exception() if the injected #PF is async page fault. Cc: Paolo Bonzini

[Devel] [PATCH 0/6] backporting async_pf injection functionality

the patch set is for 1. Replace Roman's patch avoiding async_pf injection while in the guest mode with the similar patch from the mainstream for kernel code consistency 2. Force a nested vmexit if the injected #PF is async_pf 3. Let guest support delivery of async_pf from guest mode Denis

[Devel] [PATCH 4/6] Revert "kvm/x86: skip async_pf when in guest mode"

This reverts commit 5173f45a28cdf3d5808e236eab882273a760a363. The commit will be replaced with the mainstream commit which does the same: 9bc1f09f6f KVM: async_pf: avoid async pf injection when in guest mode This is done to make vzkernel look similar to the mainstream kernel with all the

[Devel] [PATCH] connector: bump skb->users before callback invocation

From: Florian Westphal Backport of commit 55285bf09427c5abf43ee1d54e892f352092b1f1. Dmitry reports memleak with syskaller program. Problem is that connector bumps skb usecount but might not invoke callback. So move skb_get to where we invoke the callback.
