From 542060ea79c861e100411a5a44df747b56a693df Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Sat, 4 Jan 2014 18:47:21 +0100 Subject: [PATCH] KVM: nVMX: Add tracepoints for nested_vmexit and nested_vmexit_inject Already used by nested SVM for tracing nested vmexit: kvm_nested_vmexit marks exits from L2 to L0 while kvm_nested_vmexit_inject marks vmexits that are reflected to L1.
