4.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Long Li <[email protected]> commit ab60ee7bf9a84954f50a66a3d835860e80f99b7f upstream. When sending the last iov that breaks into smaller buffers to fit the transfer size, it's necessary to check if this is the last iov. If this is the latest iov, stop and proceed to send pages.
