我正在使用 Windows Cloud Filter API 创建虚拟驱动器。删除回调在 Windows Home 21H1 19043.1165 (cldflt.sys 10.0.19041.1110) 上按预期停止工作。如果我从 CF_CALLBACK_TYPE_NOTIFY_DELETE 返回错误代码，则无论如何都会删除脱水占位符，无论我返回什么错误代码：

void CALLBACK FakeCloudProvider::OnNotifyDelete(
    _In_ CONST CF_CALLBACK_INFO* callbackInfo,
    _In_ CONST CF_CALLBACK_PARAMETERS* callbackParameters)
{
    CF_OPERATION_INFO opInfo = { 0 };
    
    opInfo.StructSize = sizeof(CF_OPERATION_INFO);
    opInfo.Type = CF_OPERATION_TYPE_ACK_DELETE;
    opInfo.ConnectionKey = callbackInfo->ConnectionKey;
    opInfo.TransferKey = callbackInfo->TransferKey;
    opInfo.CorrelationVector = callbackInfo->CorrelationVector;
    opInfo.RequestKey = callbackInfo->RequestKey;

    CF_SYNC_STATUS_MSG* syncStatus = new CF_SYNC_STATUS_MSG;
    syncStatus->Code = STATUS_FILE_LOCKED_WITH_WRITERS;
    syncStatus->SetMsg(L"MY TEST");

    opInfo.SyncStatus = syncStatus;
    
    CF_OPERATION_PARAMETERS params = {0};
    params.ParamSize = sizeof(CF_OPERATION_PARAMETERS);
    params.AckDelete.Flags = CF_OPERATION_ACK_DELETE_FLAG_NONE;
