It looks like this happened because data got renamed to io_data, which made the `data = NULL` marked with "Do not kfree the buffer in this function" not do what it was hoping. This should probably either delete the assignment above or fix the assignment to refer to io_data? (EIOCBQUEUED presumably can't come from elsewhere?)
