Subject: [PATCH v3 0/4] KVM: x86: tracepoint updates

This patch series is intended to add some selected information

to the kvm tracepoints to make it easier to gather insights about

running nested guests.



This patch series was developed together with a new x86 performance analysis tool

that I developed recently (https://gitlab.com/maximlevitsky/kvmon)

which aims to be a better kvm_stat, and allows you at glance

to see what is happening in a VM, including nesting.



Best regards,

Maxim Levitsky
