[PATCH 4/6 v3] KVM: VMX: Fill in conforming vmx_x86_ops via macro |
Date: |
Tue, 28 Jul 2020 00:10:48 +0000 |
The names of some of the vmx_x86_ops functions do not have a corresponding
'vmx_' prefix. Generate the names using a macro so that the names are
conformant. Fixing the naming will help in better readability and
maintenance of the code.
