Commit Message

Tianjia Zhang April 22, 2020, 12:58 p.m. UTC
In the current kvm version, 'kvm_run' has been included in the 'kvm_vcpu'
structure. Earlier than historical reasons, many kvm-related function
parameters retain the 'kvm_run' and 'kvm_vcpu' parameters at the same time.
This patch does a unified cleanup of these remaining redundant parameters.
