[0/3] KVM: VMX: MSR intercept/passthrough cleanup and simplification

Message

Dongli Zhang Feb. 17, 2024, 1:45 a.m. UTC

The 1st patch is to fix a comment.

The 2nd patch is to avoid running into many vmx_enable_intercept_for_msr() or
vmx_disable_intercept_for_msr() that may return immediately, when
vmx_msr_bitmap is not supported.

The 3rd patch is to simplify vmx_enable_intercept_for_msr() and
vmx_disable_intercept_for_msr(), to avoid calling
possible_passthrough_msr_slot() twice.

Thank you very much!
