If this patch is always needed, then the function should be named
something like kvm_mmu_apply_introspection_access and kvmi_tracked_gfn
should be tested from the moment it is introduced.
But the commit message says nothing about _why_ it is needed, so I
cannot guess. I would very much avoid it however. Is it just an
optimization?

[RFC PATCH v7 00/78] VM introspection
The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place
