[PATCH v2 07/15] KVM: VMX: Rename vcpu_vmx's "guest_msrs_ready" to "guest_uret_msrs_loaded"

From: Sean Christopherson
Date: Wed Sep 23 2020 - 14:04:36 EST


Add "uret" to "guest_msrs_ready" to explicitly associate it with the
"guest_uret_msrs" array, and replace "ready" with "loaded" to more
precisely reflect what it tracks, e.g. "ready" could be interpreted as
meaning ready for processing (setup_msrs() has run), which is wrong.
"loaded" also aligns with the similar "guest_state_loaded" field.

No functional change intended.
