Subject: [PATCH v2 08/15] KVM: VMX: Rename "__find_msr_index" to "__vmx_find_uret_msr"
Date:   Wed, 23 Sep 2020 11:04:02 -0700
Message-Id: <20200923180409.32255-9-sean.j.christopherson@intel.com>
In-Reply-To: <20200923180409.32255-1-sean.j.christopherson@intel.com>

Rename "__find_msr_index" to scope it to VMX, associate it with
guest_uret_msrs, and to avoid conflating "MSR's ECX index" with "MSR's
array index".  Similarly, don't use "slot" in the name so as to avoid
colliding the common x86's half of "user_return_msrs" (the slot in
kvm_user_return_msrs is not the same slot in guest_uret_msrs).

No functional change intended.
