Sean Christopherson 5d6317ca4e KVM: x86/mmu: Voluntarily reschedule as needed when zapping all sptes ... Call cond_resched_lock() when zapping all sptes to reschedule if needed or to release and reacquire mmu_lock in case of contention. There is no need to flush or zap when temporarily dropping mmu_lock as zapping all sptes is done only when the owning userspace VMM has exited or when the VM is being destroyed, i.e. there is no interplay with memslots or MMIO generations to worry about. Be paranoid and restart the walk if mmu_lock is dropped to avoid any potential issues with consuming a stale iterator. The overhead in doing so is negligible as at worst there will be a few root shadow pages at the head of the list, i.e. the iterator is essentially the head of the list already.
