  Documentation: KVM: Formalizing taking vcpu->mutex *outside* of kvm->slots_lock (2026-03-02 09:52:09 -0800)

----------------------------------------------------------------
KVM generic changes for 7.0

 - Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being
   unnecessary and confusing, triggered compiler warnings due to
   -Wflex-array-member-not-at-end.

 - Document that vcpu->mutex is take outside of kvm->slots_lock and
   kvm->slots_arch_lock, which is intentional and desirable despite being
   rather unintuitive.
