[PATCH v3 0/2] KVM: count actual tlb flushes

From: Liang Chen
Date: Thu Sep 18 2014 - 12:40:13 EST


* Instead of counting the number of coalesced flush requests,
we count the actual tlb flushes.
* Flushes from kvm_flush_remote_tlbs will also be counted.
* Freeing the namespace a bit by replaces kvm_mmu_flush_tlb()
with kvm_make_request() again.

---
v2 -> v3:

* split the patch into a series of two patches.
* rename the util function kvm_mmu_flush_tlb in x86.c to
kvm_vcpu_flush_tlb

v1 -> v2:

* Instead of calling kvm_mmu_flush_tlb everywhere to make sure the
stat is always incremented, postponing the counting to
kvm_check_request.
