From: Zongyao Chen <[email protected]> KVM rejects guest_memfd bindings that overlap an existing binding, but currently reports -EINVAL from the generic error path. Return -EEXIST for binding conflicts and adjust the selftest so it actually reaches the guest_memfd binding overlap check instead of failing earlier on GPA memslot overlap.
